This game has addition and subtractions. Sometimes it gets even hard as you go through all the levels. If you see a number on the side of his head like 9 you just use 6 + 3 =9 or any thing that adds up to what the number says on the side. You could use subtracting by doing a number higher than the number on the side of his head. Pretend it says 9 at the side of his head and then use subtracting like 10 - 1 =9 http://www.coolmath-games.com/0-brainie/index.html
