Casio CalculatorWhen the sun shines, it's solar charging. Don't worry too much. The small screen of the Casio calculator is a solar panel that can be charged under a light source and not under the sun. The Casio calculator uses a large display with large fonts, clear and easy to read. You won't miss anything when you do quick calculations.
Casio calculator information
The Casio calculator display supports up to 12 digits. When choosing a calculator, be sure to select the majority number displayed. otherwise calculations that require some precision cannot be fully displayed.
There is a black bar on the display screen, which represents the solar charging panel. I remember when I used this dual-powered calculator as a child, I thought naivelyment that the calculator could not be used. if the black bar was stuck, there are also batteries inside.
Casio scientific calculators are essentially the same as ordinary calculators, and each symbol can be used normally to perform the corresponding calculations. In addition to using each key, Casio calculators also have a second function. Most cases have special fonts such as symbols and letters above the calculator.
If you want to activate the second function of the Casio scientific calculator, you must first understand the very important function key change on the computer.
