You play as Sarah Jacobs, a graduate student working at Cleveland University.  On the eve of discovering a mathematical cure for cancer, your mentor, Professor Claire Liddy, is gunned down by terrorists.  Fortunately, before she died, the Professor was able to erase many of the plus and minus signs with her bloody hands, saving the cure from falling into the terrorist's hands.  

It's now up to you to fill in the symbols, and re-cure cancer!
