@MrViveksahi So easy! This is a method of Arthur Benjamin (19 March 1961 - ) who is the author of a book using this method I have! For 714^2, do 728 x 700 and add 14^2 = 196 for (72800 x 7) + (14 x 14) = 509600 + 196 = 509700 + 96 = 509796. :P

it would actually be easier to just do a written mehod of it
e.g: 67^2= 67x67
[use written method]
