Reliable and Durable

I've had Casio calculators for years and they never let me down. This model is lightweight enough to carry in a pencil case but sturdy enough to survive being dropped occasionally.

Good for the price

Does everything a student needs for middle and high school math. The natural display makes checking work much easier. Took off one star because the manual could be more detailed for advanced functions.

Best standard scientific calculator

Simple, effective, and approved for exams. No graphing capabilities which is perfect for tests where those are banned. Fast delivery and genuine Casio product.

Exam Essential

Bought this specifically because it is allowed in standardized tests. It works flawlessly and the solar power means I rarely have to worry about batteries. Authentic product as described.

Perfect for High School Math

This calculator is exactly what my daughter needed for her algebra and geometry classes. The display is very clear and shows fractions just like they appear in textbooks. Highly recommended for students.

Great value, easy to use

I bought this for university statistics. It handles all the basic functions I need without being overly complicated. The only downside is the button feel is a bit stiff at first, but it loosens up with use.

5 FAQ

Q: Is the display backlit for use in dark rooms?

A: No, the FX-82ES PLUS A does not feature a backlit display. It relies on ambient light and its solar panel, so it is best used in well-lit environments.

Q: Is this calculator allowed on the SAT and ACT exams?

A: Yes, the Casio FX-82ES PLUS A is fully approved for use on SAT, ACT, AP, and IB examinations as it does not have graphing or computer algebra system capabilities.

Q: Does this model come with a protective hard case?

A: No, this model typically comes with a slide-on hard cover that protects the screen and keypad when not in use, but it does not include a separate zippered carrying case.
