@steveypjr

its a trick but really doesn't work for most problems, like 16*7. Its harder to calculate 160-16*3 then doing it the right way.

[steveypjr]

Why does this guy do it the hard way? 160-16 is easier and quicker.

@Dungarth I am not quite sure I get you but I think I know what you mean the way I always remember it is you always put down the number on the right(I haven,t watched the whole video btw)so say if you was doing 3 x 34 you would do 3 x 4 and that = 12 so then you put down the 2 because the 2 is on the right side of 12.(Then just to finish off 3 x 34 you do 3 x 3 =9 then you + the 1 you,ve carried which is 10 so if you put down the 10 next to the two you get 102)I hope that helps.

[Dungarth]

Can someone explain why he carries some smaller numbers when he multiplies and then carries the bigger ones? I'm confused.
