I work with a bunch of software geeks. It was someone's brithday last week and we got him a cake, one of those white rectangular ones.(adsbygoogle = window.adsbygoogle || []).push({});

Someone joked about about many pieces he needed to cut it into, someone else made a joke about matricies.

I said he had to cut it into a prime number of pieces, all the same size and shape. How many cuts did he have to make?
