I'm taking the IGCSE Maths next year and I'am starting from the basics. At the moment I'm multiplying large numbers and there is one or two ways in doing this. One is with cross and vertical multiplication but I prefer the usual way does anyone else?

yes, but knowing how to multiply two numbers is still useful.

The usual way is best, unless you need to do some competitive fast multiplication.

naturally i wholly agree with both of you.
How you choose to perform any arithmetical operation is a matter of personal choice rather than right or wrong and methods change according to teaching fashions. When I was your age log multiplication was the ONLY way, now from what I hear teacher prefer the grid method.

Yes you are right! By usual I meant the method currently taught in UK primary/secondary schools (which of course may change), in comparison to the other methods taught in places like Kumon, etc.

Might be worth checking out the Russian Peasant method of multiplication

Appropriate that you mention this, given your name.
