Calculator

A calculator is a thing which allows people to do maths operations more easily. For example, a normal calculator will add, subtract, multiply, and divide. Some also do square roots, and more complex calculators can help you do calculus and draw function graphs.

For example, if you press "3" and then "+" and then "2" and then "=" the number "5" will be displayed on the screen.
