re: Drop some of your helpful knowledge on the O-T

You can get the squared result of any two digit number ending in 5 by multiplying the first digit by the next higher digit and adding "25" to the result.

Example: 25 squared = 2 X 3 = 6, plus 25, = 625.

45 squared = 4 X 5 = 20, plus 25 = 2025.

95 squared = 9 X 10 = 90, plus 25 = 9025.
