@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
Currently studying to take the GMAT and I must say your mini-tutorials are exceptional. Thank you so much for helping me to brush up on long forgotten mathematical principles; some of which weren't that fresh in the first place.
if you came up with this method you deserve a medel of some type!!!! its brilliant, ive always found the conventional way REALLY confusing:( this is fail safe and easy to do though:) thanks heaps mate!!!
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
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.
THANK THE LORD!

Can I ask what if the sum was
5070 by 306 how do we treat the zeros ?

@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.

b. method*
c. taking*
