This problem is floating around the web: 6 / 2(1+2) A disappointing number of replies say the answer is 9. Where I come from the answer is 1. Now I will be the first to admit that I maybe I am wrong. But what is disheartening is the number of people that are on each side of the fence. If one out of 10 said the answer was 1 I would question my own answer more than I have. Or, conversely if one out of 10 said the answer was 9. But no matter how you slice it there are enough people with wrong answers out there that it really disappoints me.
