I read from Lewis Pulsipher's new book that the Y generation have problem doing mental math. Apparently some people cannot calculate a 10% tip.
So I thought that the best solution to train mental math could be done by playing st0ck t!cker without a calculator. (The way I usually play it)
I decided to write an article about it and explained how the math is done in this game.

I hate games that tell me where to go. I like to explore by myself. This is why I play skyrim in a very unusual way since I simply don't care about the quests.
