This calculator has just the right amount of functions needed for algebra in middle school and is at the right price.

This calculator does everything I need for my math classes in college and was at a great price

I like the price and they work well for my Chemistry classes.

Works great at a a great price

The Casio uses a battery but should last for years, (CMOS circuits have very low power-consumption).I bought this calculator because the price (less than $8), was irresistible!
