I wrote this script when my kids were just starting their math practice. It’s pretty basic, and is meant to be printed out, not done on the screen.
It has addition, subtraction, multiplication and division. You can set the number of questions, the range of numbers to choose from, answer limitations like positive or integer only, and can mix and match all 4 operations. It includes an answers page, so checkers don’t have to do the math themselves. 🙂
There is also a Timetables version.
It currently lives on one of the demo sites, but will probably be moved so it’s under here directly.
