There are infinitely many pairs of numbers whose sum equals their product.

However, there is only one solution to the equation below, in which each letter stands for a single, distinct digit.

AB × C.DE = AB + C.DE

What digit does each letter in this equation represent?

I*m pretty sure that a solution is: A = 0, B = 0, C = 0, D = 0 and E = 0 :)
