Amazon.com Product Description

For students in any field, but especially math and sciences, the Casio CFX-9850GB Plus graphing calculator is a problem-solving tool with over 900 features for storing, graphing, and analysis.You can execute evaluation tables on a split screen (which allows you to trace the graph and scroll table values simultaneously) to display graphs and tables. With a long list of features, you can master list-based, one- and two-variable statistical calculations, a variety of regressions, statistics, hypothesis testing, and advanced financial calculations.

The large, readable display exhibits eight lines and 21 characters (15-digit, 10-plus-2 display) in three colors. Graphing functions include rectangular and polar coordinates, parametric, inequality, and vertical lines. Since graphing is animated, you can change the variables in a formula and watch the graph move accordingly.

It also performs statistical calculations such as scatter plots, histograms, box and whisker plots, and eight regression types. The dual screen shows two graphs: a graph and zoom or a graph and table on the same display. In statistical graphing you can use list-based matrix calculations of up to 26 matrices. The list editor manages up to 36 data lists and exchanges data with matrix and table modes. An instant-replay key recalls your previous entries.

The built-in communications port enables linkup to a personal computer. The CFX-9850GB stores up to 38 programs with 32 KB total memory. It is protected by a hard slide case and powered by four AAA alkaline batteries and a lithium battery for backup to preserve a constant memory even when the unit is turned off.

Far better than a TI...
Simply put the Casio 9850GB Plus is the best performace over price value out there. Though many schools have TI centric curriculum, I've found I have an even easier time than the TI owning students because of the Casio's straightforward interface. I highly recommend this calculater, it's easy to use, as fast (or faster in my expierence) in graphing sine functions when compared to TI's, and the price is unbeliveable (I got mine for $49). My advice, go against the crowd, get a Casio. You'll thank me later.

Best Buy Graphic Calculator
I needed a graphing calculator for a math course I'm taking late in life. Everyone said go Ti. When comparing the functions of both this Casio and the $150.00 Ti, I found them to be capable of the same things. With a rebate, I only spent $40.00 for this one and it does all I need to do. If you can handle the little differences in operation between Casio and the Ti that the professor probably has, save some money. The color display makes the graphs much easier to see. Highly recommend this calculator.

Great Calculator
I bought this calculator before i enetered the 9th grade. Everyone in my class had the Texas Instruments TI 83 so i wanted to be different so i bought the CFX-9850GB Plus. It was the best desicion of my mathemtics life. Aftewr my friends saw the features and the user friendly menu they also decided to buy one. It has more features than the TI 83 and is easier to use. It is a bargain at the price it is being offered at. Even if you already have a graphing calculator i suggest buying one ASAP.

I have one and I wouldn't trade it for anything.
I bought mine to use in my classes for my A.A.S. Electronic Engineering. It has been a mind-saver when it comes to finding the answer to any equation I come across. The mathmatical features of this unit are more than enough for any field of study. I would recommend it for anyone. The only drawback I could find with this unit (as with any graphic unit), is the time it takes to learn some of the more advanced features, however, there is a very informative handbook to help you get the most out of this product. If you purchase one, you should not be disappointed.

User friendly!
I am in a college statistics class and I am glad I have this calculator instead of a TI-83 or ANY TI for that matter. My professor would give instructions for both the TI-83 and Casio CFX-9850 GB Plus and let me tell you the Casio has fewer steps almost all the time! With the TI, it is very easy to put in statistics info wrong if you cannot remember the proper order to input the numbers. With the Casio, it tells you what numbers to put where. If I had to pick between the TI and the Casio, I would pick the Casio. Even my mathematics professor recommends it for ALL of her courses. ... Read more

A trusty adding machine
I've used Casio calculators for over 20 years and love them. Good keypad layout, easy-to-use buttons, intuitive commands. This scientific calculator is perfect for engineering students.

Outstanding Casio quality for an excellent price
I have been using Casio electronics for over a decade now -- starting with first data bank and touch screen watches. The brand has never failed me, so I have chosen Casio FX-260 over TI and Sharp competitors again. The calculator is great for graduate classes in Computer Science and Finance for sure (this is what I am using it for), and I am certain it will be more than enough for Physics, Chemistry, and other sciences. Compact design, a high-contrast screen, rubber keys -- everything is just right. And if I want to do graphing, I will use Matlab. Highly recommend!

Great for the price!
Needed a scientific calculator for a chemistry course and I found this one to be very easy to use. ...

Great calculator for the price!!
This calculator is worth at least three time the price. I know of at least 2 PhD's who use it at the Colorado School of Mines. It is a rugged and compact machine that you can take into the field without any problems. I does most any calculation. For heavy calculations, I use a lap top.

Great priced scientific calculator
I recently bought one of these scientific calculators. This calculator is not only compact but it is also inexpensive. And since it is solar powered I never have to worry about the batteries running down if I leave it on. This is a great calculator to buy if you don't want to spend a lot but want to get a lot from it. ... Read more

The Casio Algebra FX 2.0
I want to begin by saying that I'm no expert when it comes to Math or Scientific Calculators. I am just a regular user of this product. I graduated High School in 1981, and I started going to a local community college in 2001. I think it's safe to say that things have changed quite a bit, I never took Algebra in High School and was very intimidated by it, truth be known; I still am intimidated. I found this calculator by doing a web search, but I could not find the calculator itself anywhere. I found it here at Amazon.com by accident. I am very impressed at what this little machine will do, it's a real lifesaver, and all my friends at school are always asking me "will yours do this kind of problem" and the answer is almost always a yes. Their TI-83's usually wont. The only drawback that I can see to the Casio is that nobody really has any experience with them, and you're somewhat alone in the learning process. I do wish that Casio would make their instruction booklet a little easier to understand. I would definitely recommend it to anyone.

For professional Usage
I have been using Casio calculators since my High School. In my engineering course I used FX-120 & SuperFx-100. While I am at job, I had to implement some complex differential equations on my software. I really got a good solution in the form of Casio Algebra FX 2.0 Plus. This product is simply the best, it solves my purpose. I could even try my algorithm even while I am travelling - hats of to the Programming feature. Please note I am making this comment for the AFX 2.0 Plus version.

The keys are smooth, grip is good. However the calculator is slightly bulky. Overall its a embedded computer fitting within hand.

SB-87/SB-155 CABLE HARD TO FIND
HERE IS A SITE WITH THE HARD TO FIND CABLE FOR THIS CALCULATOR. JUST COPY & PASTE. http://www.pccables.com/87020.htm IT IS $17.99. I LIKE THIS CALCULATOR ALOT, BUT THERE ARE A FEW THINGS THAT COULD BE IMPROVED ON IT. AND FOR THE ONE WAITING FOR CASIO TO HAVE A COLOR CALCULATOR, WELLLLL THEY NOW HAVE ONE. LOL

Don't buy this!
If you're gonna buy a graphing calc, get a TI-89, I first bought this Casio one and it's completely overrated by the most part of the people that has written here... It's not good at all.
Now I'm totally satisfied with my TI-89

Best on the market
I believe this is the best scientific calculator currently on the market. The price is reasonable, especially for those reluctant to spend ... on a graphing calculator. The keys are highly responsive and hard plastic. The layout is the best of any calculator I have ever seen. In my opinion Casio really thinks about key layout. Other calculators, such as the Sharp EL-506RB (the only other scientific calculator that comes close to this one) seem to have functions thrown across the keys wherever they will fit, without thought as to convenience or relative frequency of use. The manual is clear and concise, but the calculator is intuitive anyway. The only intructions I needed to look up were for numerical integration and entering data for statistical purposes. The only complaints I have about this calculator are lack of numerical differentiation and a constant/conversion function. If the calculator includes integration it only follows that differentiation should be included as well. Nonetheless, you can program in and save formulas for differentiation and Newton's method to keep and reuse later. The Casio FX-991w (which is no longer sold -- Why Casio? Why?) includes constants and constant conversions (the manual for both the 991 and 115 is shared, or I never would have known this.) As a physics student, I sometimes find myself needing to look at tables for certain constants and conversions that I wish would be included in the calculator. In light of the non-existence of the FX-991w, I must say that is is absolutely the best possible choice for a scientific calculator.

Best calc for middle school math
I have used many calculators through my years but this is the best simple, multi-function calculator. It can do basic functions with scientific mode and insert variables into equations. It has many features including a great 2 line display so that you can review the equation you typed in and look at the answer all at one time. It includes exponets, and the variable exponet key, spuare roots and cube roots, fractions sin, cos, and tan functions with memory and paranthesis among the basic calculator functions. I prefer the Casio to the Texas Instruments because this calculator is much easier to understand in button layout. I do not recommend this if your child is about to go to high school because when you go into high school, you will be required to buy a graphing calculator for geometry and such. Schools often require the Texas Instruments Model
TI-83 which is very pricy and has so many functions that its mind-boggling. If you need an ideal calculator for algebra or pre algebra, this is the calculator for you.

Cassio vs. Sharp
I have purchased within the last two weeks both the Casio fx-115MS and the Sharp EL-506VB calculators. If you enter (21)2 in both calculators and then press the equal key, the Casio will display "Syntax Error" and the Sharp will display "Error 1.". Why is an error message displayed in both calculators? Does this mean that there is the same "bug" in both calculators?

On the other hand, if you enter 2(21) in both calculators and then press the equal key, both calculators will generate 42 in their respective display areas. It must be that each calculator's design is such that both do not recognize an "operator" (addition, subtraction, multiplication, or division) when a number enclosed in parentheses is immediately followed by another number.

If you enter (21)2, both calculators recognize it as an error in "syntax" or rules by which either unit can calculate or perform an "operation." You did not enter an operator so the calculator cannot perform any calculation. In the first case, (21)2, no operation (multiplication) is recognized by either calculator and as a result, both units generate the "error" message. In the second case, 2(21), both calculators recognize the "operator" (multiplication) and performs the operation to arrive at the correct answer, 42.

Nevertheless, both the Sharp and the Casio recognizes the "order of operation." For example, if you enter the expression (2 +3)2 and then press the equal key, you will again see the "error" message displayed by both calculators. However, if you enter (2 + 3) x 2, you will see the correct answer displayed by both calculators, that is, 10. It is evident that any number or expression enclosed in parentheses as the first entry which is then followed by a number will generate the "error" message.

I just tried entering (2 + 3)2 on the scientific calculator that comes with Windows XP Home edition. When I pressed the enter key, the display remained at "2." This means that the computer did not recognize any "operator" after (2 + 3). If you enter "(" then "2" then "+" then "3" then ")", you see immediately that the result of the operation is 5. Go on and enter "2" and press the equal key, and you see that nothing happens because you did not enter any operator (multiplication) after 5. You are stuck at 2. While the calculator in Windows will not generate an "error" message on the one hand, both the Sharp and Casio will to let you know that you have violated the "syntax" or rules used by either calculator. Remember, a calculator is just a dumb paper weight and it won't do anything for you until you tell it exactly what to do. However, both the Sharp and Casio will perform various calculations for you but will only follow the "syntax" or rules incorporated in their respective designs.

One feature on the Sharp that I really like is the fact that each numeral or expression you enter is displayed in the lower line of the two line display before you enter an operator. This allows you to see and make sure you are entering the correct data. Once you enter the correct data and follow it with some type of operator, the data you entered appears on the upper line of the display area. This allows you to "double check" all entries before you press an operator or equal key. The Casio fx-115MS on the other hand shows all data entered on the upper line first just as you enter it in the calculator.

I like both calculators equally well, and both have their advantages and disadvantages. But the advantages and disadvantages spring mostly from user preference. For me though, the Sharp EL-506VB has the edge because it comes with more thorough and user friendly documentation explaining each function more thoroughly than the Casio fx-115MS. So for five dollars more the Sharp is worth it.

The ... Casio graphing calculator also looks like a good investment and seems to come with a very adequate booklet of about 150 to 200 pages. That will most likely be my next calculator.

great calculator for the price
I'm amazed by the features in a $15 calculator. Basically all casual lab calculations I need are handled by this one. Of course it has all of the standard scientific/trig functions, plus a stats mode for mean, std dev, linear regression, etc. What makes it really great is the simultaneous equation solver for 2 or 3 variable linear equations, the quadratic solver, and the cubic (!) solver. Yes, you can solve these analytically pretty easily, but after awhile it gets tedious and you just want the answer.It also lets you enter an equation and solve for any variable without isolating the one you want first, though this is a bit less successful. The numerical integration feature is nice, though the algorithms for these last two aren't as robust as those of the old hp series (eg math error on I(0,1) [sinx/x) dx]). Also does numerical derivatives, fractions and complex numbers, though I have no need for these. The manual is pretty skimpy, but you can't expect much at this price. It's very easy to use and prompts for variables it needs.
In summary, makes a great lab calculator, and any calculations it won't handle are probably best done on a computer anyway.

Terrific School Calculator
I bought this calculator from Staples for $14.99 on August 11, 2001. Then, I lost it about a week ago lol. After having it for two years, I'm VERY pleased with it. The look of it is a lot better than the Texas Instruments and all the buttons are in the place that you would put them if you were designing it. The two-line display works great and you can recall up to 8 problems on the calculator. The only drawback is the battery dies out after awhile, but then the solar panel comes in handy. Overall, this calculator is great. Any Casio product I have liked. Since I found this on Amazon I think I'm going to purchase another one as a replacement. I recommend it. ... Read more

The perfect calculator for up to 8th grade
This calculator is easy to use and had good button feel. It does fraction calculations (a great function for students under 5th grader who are just learning about fractions but don't know about decimals).

First Graphic
I purchased mine for $49. Its suitable for any classes through college algebra. For trig you'll want to upgrade as it doesn't graph polar coordinates though it does convert rectangular to polar and back. If you needed to you could program it to input the (x,y) into a parametric graph and so display the results.

While my class mates were worrying about how to get their TI's to work I was working on the problems. Even though I've moved to the Casio AFX 2.0, I keep it for a backup. When my buddy isn't borrowing it...

Memories?
This calculator has many good features. Large enough for keys to be easily used, but fits in a shirt pocket. Uses two cheap AAA bstteries with a button battery for memory backup. It has a detailed instruction book, But the MEMORY is next to IMPOSSIBLE to access. The calculator does not even use the word memory, but uses the word list. It goes in to great detail how to manipulate the data in the list, but does not have a store or save and a recall button I spent 2 days trying to figure it out, and finally took it back. The HP9g that I replaced it with was easy to enter and access memory.

it barely does its job
studying A level maths i thought a graphic calculator would be fairly useful, and it was for a while. But with its poor diferentiation capibilitys and total lack? of intergration one. My advice if you were thinking of buying one of these is spend a little extra money and get a Ti-83

slow
Other than students few need, or can use graphing calculators.
Although this calculator is advertised as being useful up to and including the calculus it is best used in Pre-Algebra and Algebra I. This is a very inexpensive graphing calculator and is, thus, very slow, the screen is pretty hard to read and the instruction book not only hard to follow and very demanding but printed on paper so thin that one can read the second page through the first.
After buying this calculator neither my 14 y.o. nephew nor I know just where it 'fits'. He reports that its slowness yields it fairly unhelpful in class. I prefer the entry system of Hewlett Packard RPN.
We conclude that this calculator is best used for simple non timed investigation of numbers and their relationships to one another as in 2 + 2 = 4
A good pre algebra calculator, a pretty good algebra calculator ad for the price ... unbeatable.
A good choice when calculator theft is a real possibility.

Ok For Algebra
This is a very limited calc. It dosen't have many functions nor programs. If you want to get a easy simple calc for like algebra this is good but if your in trig or calculus get a TI not this. ... Read more

Low cost high performance.
This calculator was recommended in my undergrad engineering lab courses. This calculator served well in preparing for reports in the courses. Low price but very sophisticated. A must for students taking lab courses. ALENCIOUS SHU ZEE LO is WRONG!

ALENCIOUS SHU ZEE LO is WRONG!!
I just got my fx300w and was trying to replicate the bug ALENCIOUS reported. I found actually he/she misunderstood the functions. By RCL you only see what's stored in those alpha memory spots. If you wanna use them to calculate, you do not need to recall and cal( this will actually become what in ANS calculate with the last alpha u enter. The correct way to do calculation is just press Alpha and the spot u want to cal. In ALENCIOUS's example, it would be 'Alpha A + Alpha B', and that's absolutely correct.
Overall, I think this calculator is [inexpensive], convinient and powerful. I like it more than my TI-82 and also more than the new casio MS series(fx-300ms) :). Enjoy!

Be careful on the bugs of this calculator
Ok, this calculator looks great value with the amont of features, but it also have a very serious bug. The Store and recall function will give you a wrong answer if you do something like this:1 STO A2 STO BRCL A + RCL BThe answer depends on a previous calculation.As a summary, buy this calculator only if you think that money is more important than your projects, grades etc.

Superb Calculator!
I used to own a TI-36 made by Texas Instruments. That was a nice calculator, but then I decided to upgrade to this calculator.

There are many differences that set this calculator apart from the TI-36.

First of all, I love the 2 line display that displays the equation or whatever you just typed in on the top line and the answer on the bottom. Makes a perfect alternative to a graphing calculator that is very similar by displaying whatever you originally typed in. The TI-36 did not offer this. THis is a big plus.

Also, whenever you need to indicate a negative value, you can either use the negative button or the minus button before the value... for example, if you wanted to enter -5, you just have to key in - 5. With a TI calculator, you have to key in the five first, and then the negative sign. The TI way used to cause me to make some errors, but the Casio way is very logical!

Finally, you can use this calculator in any lighting condition. Because of three way power, you can use the solar panel in bright conditions and battery power in dark conditions, all automatically without any user interference!

There are tons of calculations that you can do with this calculator.

Although this calculator may seem a little expensive for a scientific calculator, I highly recommend it! It is definitely worth the money! ... Read more

This calculator is very good. It is very durable (i have dropped it and kicked it still works great. It uses solar power but has a battery for backup inside which i have never has to replace. The button are nice and big along with the screen. Its easy to read and the screen has a small tilt which is great when using on a desk. I love this little calculator!

Excellent produst that takes abuse
I have had this calculator since 1991. I use it alot and I have had it in my car since the day I bought it. I purchased several more to keep in my office and around the house. I especially like the big numbers for easy reading and the the big keys spaced far apart so you don't have many missed entries. You can buy alot of cheap calculators but none so easy to use and so long lasting.

a classic!
Back in 1983 (if you can believe it), I bought a used Casio SL-300 in a suburban garage sale... I had never heard of, nor seen, a solar powered anything... I thought it was miraculous! Those were the days of big lunky Texas Instrument units that took batteries. Today, I was just doing a search to see if I could find the original on the internet, and I see they're still making it, with only minor design modifications.

I still have it, and it still works. How can I ever get rid of it? I swear, this is the most reliable electronic gadget I've ever seen. Can you believe a 20 year old solar calculator still works? Shocking! ... Read more
