Three 2's
Here's a fun little problem:
Show how you can get any positive integer, using only three 2's and any mathematical operations.
For example, 2+2/2=3 generates 3, but we need to find a solution that can generate any integer.
Answer
Pretty ingenious, no? ;)
BTW, I couldn't get this problem either - my math teacher showed me the answer.
