A really handy app

Ive spent countless amounts of time on the internet searching for math tricks that could ease and facilitate the everyday calculus we bump into. Mathemagics embraces most of the interesting ones for an affordable price. The interface is friendly and the exercises help us to fix in mind the lessons presented. I highly reccomend it, just made calculation funnier than evet.
