I love it because it is so fun and very little math because about every wave you get about 5 math questions and I play it at school because it is fun to play but at school there is only 4 iPads.I also almost bet the game but my friends say it is a dumb prize I don't even know what it is when my friends show me.

Fun, but try this

I love this game, it makes math fun. But while I was playing I ran into a weird easter egg. When the math problems appear pause the game, then wait for a few seconds. Then unpause it and do this for the rest of the level. At the end a weird/creepy slideshow will happen and will bring you to level ??. Try this it is really weird.

I'm 13, and I hate math but...

Okay, so one day in math class we had to use the iPads for something. That program wouldn't work, so since it was a substitute teacher she told us we could play games (as long as they were educational, of course.). Me and my friends decided to play this game, and I must say... It's frickin awesome!
