The math works like this Lets call the original two digit number x, then adding a "3" to the right of x would translate into x*10+3 hence we have x = (10x +3) -372 x + 372 = 10x+3 372= 10x+3-x 372-3=10x-x 396 = 9x 396/9=x x=41 and if we test it, 41 with the added 3 would be 413 and 413 - 372 = 41 is true The original two digit number was 41
