Yes 11 times tables are dead easy to start off with. Sure you're good at it and can do it up to say 12 numbers. But can you figure out 11 x 23 in just two seconds? How about 11 x 256 in just six seconds? Or how about 11 x 8762453901288321?
Well I just taught how to solve these in a quick fashion to an ordinary 10 year old kid, who was struggling in his year 4 maths, in just one day.
And guess what, I'm going to show you how.
