Math: Soul Eater Style

This for a math project. We are supposed to design a poster have it teach the reader something about math. So far, this is what I have. It's due on Thursday.

I'm requesting a form of critique in the comments please, I want to know how good (or bad) it really is and what I should change. THANK YOU!

EDIT:
Got a 95 on this, THANK YOU YOU ALL!!
