Nov 9, 2009 - Great job, but i find it easier and i do it faster by the old 104x104 way, even mentally, not on paper

Nov 9, 2009 - I've got the hang of it, but I just wish I could do it for more numbers than just what is close to 100

freestyle095 Says:

Nov 17, 2009 - so it only works for numbers within the 100s?

pitmoor Says:

Nov 18, 2009 - also another way not so smart but prety helpful is for eapmle 104 sqared=(100+4)squared=100squared+4squared+2x100x4=10.000+16+2x400=10.000 +16+800=10.000+816=10.816.you can do that in mind prety east because 100 scuared is easy to find so is 4 squared and 2x100x4..that works for everything

Nov 20, 2009 - works in the 90's too, and the 80's too, but they are harder... if its is below 100, don't add but subtract instead. (99)(99)=9801 99 - 1 = 98 1 x 1 = 1 98 01 = 9801
