Moodle Math Question Generator

I've created a numeric question generator for Moodle that will create MoodleXML files that can be imported into your course.
It will create addition, subtraction, multiplication, division, powers, and square root problems based on the upper and lower bounds of numbers that you give it. It can also limit the answers to only positive numbers and/or only integer answers.
