Math simple

This is a math puzzle game that starts easy with addition and subtraction. Later levels, which use multiplication and division, might have you scratching your head trying to solve them.

It's easy to play! Just click on the numbered objects. The operation on the object you click will determine how the total is affected. For example, if an object with "+5" on it is clicked, five will be added to the total while if an object with "-5" on it is clicked, five will be subtracted from the total. Don't let the total go below 0 or above 20.
