Calculator

A calculator is good for working out maths problems.
It has the numbers up to 9 and = + - / and on/c. It has a screen at the top so you press the buttons you want to get the answer to a maths question. It is solar powered.
You have to push the buttons you want like 5+3= and then the answer will come on the screen.
Most times a calculator is used for maths and science to get the answer to maths questions.
I think it is okay but sometimes it gives you too many numbers like 37.9999999.
