What is equal to 84 and 180?

Answer 1

-- The only number equal to 84 is 84.

-- The only number equal to 180 is 180.

-- There's no number that can be equal to both 84 and 180.

performed on 84 and 180, "and" is not a mathematical operation, so

there's not enough information to do anything with.
