not sure what you mean , but i've always known it as the Russian method others know it as the Chinese method. It also serves to explain why the traditional "english" method works.
Whatever "trick" or algorithm you use if it's efficient and this has been proved to be as efficient as traditionally taught methods, and it works then use it if you like and and don't if you don't.
PS - nowt to do with the yanks

@v5mark The method will work for any numbers, just use a four by three sized grid and remember anything multiplied by a zero is zero.

What is the first method called?

@anneschoice This grid method is apparently known as a variety of names. i was first introduced to it as the Russian Method but I have no idea if that has any substance. The traditional method in the other videos doesn't have a name as far as I know other than Long Multiplication

u know when u add up from the question 23 x 47, you the 0 on it self is a 1, but i tried that for the question 28 x 23 and that 0 wasnt a 1 it was meant as a 0 ? hw cmes
kooneyak1 2 years ago
The reason the 0 became a 1 was that the diagonal before added up to 10 or more and so you have to "carry" the 1 into the next diagonal. In your example of 28 x 23 the digits in the penultimate doagonal only add up to 6 so there is no carry
