The capabilities of the calculator are limitless and impressive. It is not limited only to mathematics, but also includes tools for chemistry and programming. Like a portable computer.

The supplier states that the color of the device I ordered was black. The device I received was white!

Cheap you can't call it, but for what it does-offers it is excellent! The best nonCAS that exists.
The menu requires familiarity if you come from simple scientific calculators, but the capabilities are endless. It has up to 3D graphics and micro-Python language for programming, as well as connection to PC via USB. Its 16MB memory is satisfactory and you can store not only programs or calculation types but also photos (after conversion with CASIO software).

You can download the Casio emulator from its website for computer (90 days free trial) and see how it works.

The extra bonus now: With a very easy process and a relatively small file of 2MB, you also acquire CAS (Computer Algebra System) for symbolic calculations (it solves even differential equations - symbolically). Search for xCas on Google.
