Customer Reviews

It is very easy to use.
Alla Hayrapetova
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!
Z. Mahdavi
The buttons are easy to press, and there are 2 lines of the display.

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!

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!

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!

This is a great little scientific calculator.
The buttons are soft and precise. It has all the functions that a student needs for Math.
The protective cover is strong.
I have no hesitation in recommending this unit.

My new school forced me to get a scientific calculator after using a graphing calculator (TI-83) for several years. Using this calculator is a breeze. I now prefer to use it over my TI. The natural textbook display allows one to input a long formula error free. I highly recommend this calculator.

4 of 4 people found the following review helpful By Carlton C. Stedman II on January 19, 2009
I've had this calculator since 2003, and it's worked great since then. It replaced a graphing calculator (TI-85), and I haven't gone back. Used in high-school, throughout undergraduate college and now at work as an electrical engineer and in graduate school.

Engineers will appreciate the easy to reach ENG button to get results in easy-to-read engineering notation. I use this day-in and day-out, dropped it countless times and have never had to replace the batteries, thanks to the solar panel. Display contrast is great and easy to read. I often keep it in my back pocket and it's sturdy enough to have survived there for the last 5 years.

Two-line display with backtracking, long input allowable, does everything I do on a day-to-day basis as an engineer.

Sure, doesn't graph, doesn't do symbolic or linear algebra (matrices), but if I need to do that, I'll be in front of a computer anyway and fire up Excel, Matlab/Octave, Maxima, et cetera. Doing that stuff is a pain on a calculator anyhow.

Overall: excellent, reliable, inexpensive, sturdy calculator.

This calculator accompanied me through high school along with all the standardized tests. I love it for all its functions (there's a lot, if one ever kept the manual and read it =) ). I really like the top line that shows you your inputs, so that when you get an unexpected answer, you'll be able to find the problem.

The only reason I bought a new one was because I misplaced my old one. I expect this one to last me at least decades since battery life has been a non-issue. This will be the only calculator I'll ever carry and use. Even now, I use it in grocery stores to figure out unit prices.

Please look no further. This Casio is the best darn calculator you can find out there for such ridiculously low price. We have had two of these babies in the analytical chem lab at work for more than 2 years, and they are always handy no matter what operations we throw at them. I particularly like the two line screen and the statistics calculations are a breeze. Dual power supply, so bright or dark they always work.
