I'm working my way through college mathematics (currently in Statistics and Calculus), and this calculator has never let me down. It is so easy to use, that it usually takes me less than a minute to figure out (or research) how to perform an operation while the rest of the class struggles with their ancient TI calculators. Highly recommended!

Casio FX-CG10 Graphing Calculator. This is a cheap but fully functional calculator. the graphic display is excellent. With this price and you get a colour screen, what a deal! This calculator is easier to use than the TI. When compare with the older TI model, this one is sure a winner.

I love this calculator. I have not had this very long but there are two things I really like. One is that I can enter fractions and radical symbols exactly like I do on paper which is much easier for me to read and keep track of. The other thing that I like is that when graphing multiple functions, they are drawn in different colors so I can compare them to each other... very nice.

I love this calculator infinitely more than any TI I've come across. The interface is very intuitive though overwhelming at first. The simplification on trigonometric and algebraic functions is bar none. The bright backlight is great for a midnight crammer, and it's extremely versatile and open functionality is amazing. I haven't fully dug through this thing yet, but I have a feeling this one will still be with me when I'm writing out my dissertation.

LOVE this graphing calculator. I purchased this calculator for my precalculus class in college. The Ti graphing calculators were suggested but i didnt like the idea of paying $100+ for a bulky outdated calculator when there was this new updated casio one on the market. the price is better and the quality of the work this caculator produces is way more up to date. why is Ti still with black and grey? this casio calc has all the functions of a Ti but just more advanced. ive never used or had to use a graphing calc before so i had no idea how to use it at first but after following youtube videos i was able to figure it out. i took the chance of having the only NON Ti in the class because i feel like Ti should have upgraded years ago, and i love it. take a chance on it. you wont be dissapointed. im glad i never went the Ti route.

The product was perfect. Very useful calculator, I strongly recommend it. You can download calculator's manual for free on internet (as well some functions)

Amazing display. I have long been a fan of the easy to use interface that the menu driven format Casio uses. I have also always been impressed with the product and training support Casio provides. This calculator's display as AMAZING. Sharp, clear.
As for those folks who say you MUST have another brand to go to college/do real math/whatever. WRONG! I have used/taught with Casios for years and my students do quite well. My own children used Casios all the way through college. The last person who told me that picked up my 15 year old Casio and was amazed at what it could do. Another teacher stuck on other brands declared the Casio "illegal" because the Casio did "too much." Technology moves on. Move with it. This is it.

Best calculator I've owned, extremely user-friendly. It may look confusing at first but it gets really easy to use once you get the hang of it. Two of my favorite features is that it factors and can solve imaginary numbers (a+bi).

UPDATE: After using this in school and playing around with it I've noticed this thing is an absolute monster. It does conversions (like time, mass, energy, etc.) and also easily input programs either yourself or via computer, regardless this is an absolute life saver and highly recommend over any TI product on the market. It is very, very easy to use, it just requires a bit of exploration throughout its features.

Is a great product, the screen is good and nice. You can download add ins for CAS, games and other utilities. Is really nice and kind of easy to understand if you read the manual.

This is for my daughter who requires (AP Physics teacher required) a graphing calculator. It works, but it requires 4 AAA batteries. Personally, I prefer RPN calculators. I have an app for that but phones not allowed in class and tests.

Let me begin my review on the Casio calculator was talking about the simplicity it brings. The simplicity of being able to write on a calculator as simple this is great. It is a stable graphing calculator that sits on a table and buttons are's real simple to manipulate. I am currently using it in my statistics class and have found that it is a wonderful tool. The grafting comes in many colors and the input method is near to perfect. There is so much that can be done on his calculator it it is exciting. I would definitely get this calculator of four star rating primarily because of five-star rating is perfect. A perfect five star rating is near impossible so a four star rating is exceptional.

Very nice graphing calculator. Color screen is great. Font size is easy on the eyes. Much faster than TI 83 and 84 calculators. Lots of functions available on same page makes is very easy to use.

Casio FX-CG10 PRIZM Graphing Calculator. I've owned and been happy with several Casio calculators before, but this is one to avoid. The menu system is complex and confusing. The printed instruction manual cannot be read unless you have a magnifier handy. Overall, look elsewhere for a graphing calculator.

Despite my instructor only teaching with Texas Instruments, I can always figure out how to use casio. I especially love their scientific calculators where I am able to solve algebraic equations and determining true/false equation. Even some simple distribution problems and the layout...its too much. ABSOLUTELY better than TI i do not know why Casio is not the standard...

Excellent calculator, I am an engineering major. I am entering my senior year at university and can say with absolute certainty that this calculator has improved my GPA. I am able to save formulas into this calculator if I am having trouble memorizing them. Some of my professors say that graphing calculators are not allowed, but have not given me trouble for using this (so long as I am quiet about it). If need be, you can put this into test mode in order to limit its capabilities, and any teacher/professor should be satisfied by this, as you cannot simply switch back and forth.
