“Reliable, Easy-to-Use Scientific Calculator!”
purchased the Casio scientific calculator for my son, and it has been an excellent tool for his schoolwork! The calculator is incredibly user-friendly, with clear, well-labeled buttons and an intuitive layout that makes it easy to use for both basic and more advanced math problems.The display is large and easy to read, which helps reduce errors when solving equations. It has all the essential functions needed for algebra, geometry, trigonometry, and other subjects, and it handles complex calculations effortlessly.One of the things I really appreciate is its durability. It’s sturdy, compact, and fits comfortably in a backpack or desk drawer. The battery life is impressive, and we’ve had no issues with performance, even after months of heavy use.Overall, this Casio scientific calculator is reliable, affordable, and perfect for students and anyone needing a dependable calculator for everyday math. Highly recommend it for both school and personal use!

Works as expected
A simple calculator for those who don’t want anything fancy. Solar battery is relatively sensitive so you can work in almost any lighting other than dark. Lastly, works fast and comes with manual to change around settings like radian or degree mode, etc.

One of the Best Scientific Calculators in its Class
All of the key scientific functions packed into a purely solar-powered calculator that actually fits all the way into a shirt pocket. That’s right, no internal battery, and it’s thin and small. An easy to read one-line display. Along with scientific functions, it can do some stats and has a random number function. It does polar to rectangular and rectangular to polar conversions. At under $10, get one for home and office.

Great calculator, with not so much scientific stuff that you need to be a genius to use it.
This is the exact same unit as one I purchased years ago. And I like that a company is making the same product because it’s a great unit. So many companies have to change things that designed well and work great, and then when they ” improve and update ” it , it becomes a piece of junk. But not Casio, they still make it the same way, with the most minute cosmetic changes.Though I use it for the most basic math, I like the scientific functions because they remind of being a math nerd.

The cover jams
I had to use a screw driver to pry the cover open. When closing, there is a first click about1/4 ionch before the cover closes completely. Thisn is the position I will be using as the it holds the cover in place and opens easily.If I click it the final inch to cover the keyboard completely, I have to find something made of metal to pry. it open again.Otherwise, for ten bucks, a good value. Check the keys to make sure it will do what you want.

Small and fully functional
Keep one around. Never know. Might learn high math. Needs a math book with it like the texas insruments ti 30 used to do with a gift case and all. Same calculator only smaller with lcd display and solar power.

Small…not made like they used to be
I used an old Casio fx300 from about 1993 until now when the flip cover broke. I thought this would replace it. This Casio is small and feels cheap in your hand. Not a smooth click of the buttons…more clunky. I was just about to take an exam and the screen froze on 60000 and took about 5 minutes of covering the solar cell to turn it off, clearing, and hitting every button to finally get it to clear. i lost all confidence in it. It has all the functionality needed for algebraic and geometric calcs, but I will definitely try to find one a little better.

愛用してきた電卓が壊れてしまい、思い切って初めてのポケットサイズ電卓。関数電卓としてはかなりコンパクトで、この小ささが魅力。あと、ボタン配置が本当に実用向き（教育向きではない）。人によっては慣れるまでにやや時間がかかるかもしれないが、これほどパチパチ使いやすいものは初めてだった。それにしても、どうして日本での販売をやめてしまったのだろう？
