What times what equals 33

If you're comfortable working with fractions and decimals, then

there an infinite number of possible answers.

If you just want to stick to whole numbers, then there are

only four possible answers:

1 x 33

3 x 11

-1 x - 33

-3 x - 11.

(Of course, each pair can be turned around and multiplied

in the other direction. When you're multiplying, it doesn't

matter in what order you line up the factors.)
