Any educational game which gets children interested in solving arithmetical problems, is, in my view money well spent. Happy Math is aimed at youngsters who are just starting to work with figures and the problems are therefore fairly simple.

The child can choose to carry out addition or subtraction at three levels, easy, harder and hardest. The thing I liked most about this program was the excellent use of graphics. If the correct answer to a problem is input, you are presented with a smiling face and two hands, one of which waves at you.

Symbols such as aeroplanes, ships and steam engines appear on the screen to demonstrate how the answer is arrived at, for example, four aeroplanes followed by six sailing ships.
