Write Math Problems

I need someone to create 250 math problems using Moodle's Formulas question type. The most important characteristic of the formulas question type is that it randomizes the values in a question. So, every student gets a different version of the question.

You can find guides and web pages on how it works. I will provide a source for the problems, however, the problems at the source will not be randomized, just certain values. You need to create questions that will randomize the values.
