See? We need a new contest called "Putnam Jeopardy".

I'll take "Small Squares for 300".

<bronk!> "What is 2+2?"

Sorry no.

<bronk!> "What is the base of the binary system?"

Sorry no.

<bronk!> "What is the number of units in the ring of integers?"

Sorry no. The question we were looking for was
"What is 5^2012 mod 7?" John, you still control the board.

I'll take "Stupid integral tricks for 600...."
