To find the square of any number with 2 or more digits with 5 as the last digit.

15 ^ 2 = you multiply 1 x the next number (2) + 25 = 225
25^2 = you multiply 2 x the next number (3) + 25 = 625
35^2 = you multiply 3 x the next number (4) + 25 = 1225
...
95^2 = you multiply 9 x the next number (10) + 25 = 9025
and on and on.

this is very good information.

Please explain the reverse process - that is, finding square roots of numbers ending in 25.
