Calculating Square of numbers quickly...
Lets calculate the square of 54
So (54)^2 = 5^2 +4 -- 4^2 = 25 +4 ----16 =29-------16= 2916
So (54)^2 = 5^2 +4 -- 4^2 = 25 +4 ----16 =29-------16= 2916
(55)^2 = 5^2 +5 --5^2=25+5------25=30---------25= 3025
(56)^2 = 5^2 + 6--6^2=25+6------36= 31--------36= 3136 etc..
