A number minus 100 is a square number, minus 63 is also a square number, how much is this?

The first square number is B2, the second square number is A2. From the meaning of the question, we can get: B2 + 100 = A2 + 63, A2-B2 = 100-63 = 37, that is: A2-B2 = 37 = 37 × 1. Considering the parity, we can see that a = 19, B = 18, this number is A2 + 63 = 19 × 19 + 63 = 424; a: this number is 424
