I just came up with a trick question. Let’s see if you can solve it.
Why will 20 become smaller when you add another zero?
Update: Commenters have been very creative. My original solution was to add the zero at the front, yielding “020″, which is 16 in many programming languages. Other solutions are “20^0 = 1″ include “0.20″.
