When the numbers we are multiplying are separated by 2 (for example 7 and 5), then multiply the number in the middle by itself and subtract one:
5×5 = 25 is just one bigger than 6×4 = 24
6×6 = 36 is just one bigger than 7×5 = 35
7×7 = 49 is just one bigger than 8×6 = 48
8×8 = 64 is just one bigger than 9×7 = 63
