This Casio is a scientific calculator. It’s more advanced than the simpler or more basic calculator models most adults use to balance their checkbooks or to add a grocery bill while shopping.

Don’t be put off by the most advanced features of a scientific calculator. When you take a GED mathematics practice test, you’ll see that the functions you need aren’t too complex or too different from a basic calculator.
