1. [a3b] - [ac] = [aa9]
100a + 30 + b - 10a - c = 100a + 10a + 9
21 + b = 20a + c
So clearly we need a=1, and that means c = b+1. There are multiple solutions to this problem.
(138 - 19 = 119, 137 - 18 = 119, etc.)
100a + 30 + b - 10a - c = 100a + 10a + 9
21 + b = 20a + c
So clearly we need a=1, and that means c = b+1. There are multiple solutions to this problem.
