Messing with major educational giants: Early April Fool's Day mischief

So today as I was working on making a test for my algebra class I came across a site that had an equation editor...naturally drawing me in of course.
While there for no more than 10 seconds a chat window popped up asking if I wanted any math help. I could have ignored it but I needed a diversion and below is the result.
I was surprised I got as far as I did before they asked for a payment since I started by saying I needed help on a test I was taking...this being a company I know for a fact already makes a lot of money through the educational system.
