As originally presented to the Internet (post 46 I believe), there appears to be spaces left and right of the ÷ symbol, and no space between the first 2 and parenthesis. If no space between, you complete the parenthetical first and the correct answer is 1. If you type the whole equation with no spaces, the answer is 16.
Simple, really, it's all about appearances. If I were more purdier, I could give a better answer.

Space don't mean ****.
