Need to create a qui question in Moodle 2.0

[bigbritboy]

Helo, i would like to know how i can create a question for a quiz. The question would create random whole numbers{X} which the user must multiply by a constant number{Y} with a value of say 17 as an example. I am relatively new to Moodle, but i can create a course and quiz, just having problem creating this kind of question. Any help is appreciated, thank you.
