Picture of How to Multiply
There are several useful methods for multiplying.

This one is one of the most space-consuming, but is also one of the easiest, as it only requires you to know your tables up to 9x9.  This makes it especially useful for KS2 or less-able KS3 students (age 9+)

The rest is adding.

Step 1: The grid method.

The method has several names, but is most often called the grid method.

To multiply two numbers together, the numbers are first broken down into their component place-value chunks.

For instance, let us multiply 47 by 68.

"47" is actually "40 + 7" and "68" is "60 + 8".

These numbers are written into a grid, as in the illustration below:

No - that linked method looks like a variation of Napier's Bones.

Nice! This is a really cool method.

It's supposed to be for kids who can't do the traditional "columns" method, but it is popular with all our kids, and I have even caught our head of maths using it.
I used this method for my maths GCSE yesterday - but I had been told it wasn't the 'right' way - so I did the other method next to it

As long as both methods gave the same result...
They did ... luckily :)
heh, when I was a kid, I never paid attention in class, and came up with my own way of multiplying that was very similar

x 47



I got points taken off for not doing it right :-(

The current policy in the UK in my school in my lessons is "if it works, it works".

I don't mind how you get to the right answer, as long as you know how you got there, and could get there again.

I normally find the right answer, then it runs and hides from me.
