I put my math worksheet generator online. I wrote this program to generate printable math worksheets for my son. For now, the options are pretty limited: it either generates addition, subtraction, or multiplication problems. Each page contains sixteen problems. The addition and subtraction problems use numbers from 1 to 999. The multiplication problems are single digit.
