HippoMath is an eToys game that tests math.

The program creates math problems that fit several settings.

Several numbers appear on screen, and one of them is the right answer.

The player controls a blue hippo with the arrow keys or with the circle keypad.

When the hippo gets to the right answer, a new problem appears.

By default, HippoMath has addition (0+0 to 50+50), subtraction (0-0 to 100-50), multiplication (0*0 to 10*10), and division (1/1 to 100/10). Addition/subtraction or multiplication/division can be turned off. The ranges for each can be changed to make simpler or harder questions, including questions with negative numbers.
