Test contest - (;) Semicolon Math

Hi, we're currently running a test contest. Click the contests tab for more details. You will have 10 minutes to solve the problems, but they are very simple. More details can be found on the contests tab. EDIT: Sorry about the contest going down for a few minutes, there was a small bug involving the timers. Nothing serious. EDIT 2: forgot to add problems in the contest. sorry.
