He might.

Here is another Math problem:
9 balls. They all have the same shape, color, etc. The only difference is that one of the balls is a little bit heavier than the rest, by so little, that you can't even tell. The rest 8 are equal. You have a classic scales like the ones in the picture. You can only use the scales twice to figure out which ball is heavier. Go ahead.
