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.)
