Vedic Math Example:

Square's of numbers that end in 5:

25²=625
35²=1225
45²=2025
55²=3025

probably some errors above but the logic is for these numbers that end in 5 and are squared the "right hand" side of the answer will always be 25 and the "left hand" side of the answer will be "left hand" of original number mulitiplied by it self pluss 1.

Say 35 → 3*4=12 → 1225. Or 45 → 4*5 = 20 → 2025..
