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)=980199 - 1 = 98 1 x 1 = 198 & 01 = 9801

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

so it only works for numbers within the 100s?
