Brain Test - Math Game description

Hello. We made a math puzzle game.

This game is to find the hidden numbers behind the alphabet.

For example, there is an math equation AB+B=BA.
Can you find number of A,B (A : 1~9, B : 1~9)
How can we solve it?

1. B + B > 10. because, tens digit A + ___ = B. so we can think it.
2. A + 1 = B. because, A + (carry) = B. so A , B can be { (4,5), (5,6), (6,7), (7,8), (8,9)}
3. B + B = 1A . so A,B is only possible 8, 9.

A = 8, B = 9.
