To square any number ending in 6; i.e. 16, 26, 36....96...156..., first square
the prior number that is ending in 5 (using the trick “squaring numbers ending in 5"), and then add the number and the prior number
to it.
For example: 462 =?
The number to be squared
is 46 and its prior number
is 45. Finding Square of 45 is simple as it ends in ‘5’ (squaring numbers
ending in 5).
So, 462
= 452 + (45 + 46) = 2025 + 91 = 2116
So, 1962 =?
1962 =
1952 + (195 + 196) = 38025 + 391 = 38416
