Mainly when working with computers. Occasionally I've seen some olympiad-type problems that involve working with different bases.
We use base 10 (decimal numbers on a daily basis. Other bases, especially 2 and 16 (and sometimes 8), are often used in computer science. You don't usually need other bases, but to avoid confusion, it is good to know the general theory.

Or vice versa. * There are lots of other situations where opposites are involved, but you probably get the idea.
