In the multiplication probelem at the right,A,B,C represent different nonzero digits. Each time the same letter appears it represents the same digit. Find the 2 numbers represnted by AA and BC.(0 is zero).
A A
x B C

B B O
A A

6 6 0

If A*C is 10, then a or c is 2,5
which means BB is 11
Because A+B is 6 without a carry, then
if A is 5
AA=55
BB=11
BC=12
Your teacher is too easy.
