Here's a program which proves that computer-aided math practice need not be boring. In the guise of a game, MathMan teaches multiplication facts by presenting random problems. The player types in the answer and presses RETURN. If he is correct, his friends gathered below cheer, but if the player fails to guess correctly, one of his friends will run away in shame.
MathMan was written by Andy Hayes and published as type-in source code in Compute! Issue 29, October 1982. Source code versions were provided for VIC and Atari 8-bit systems.
