Multiplying 2, 3 and 4-digit numbers may seem daunting at first, but it’s easy-peasy once you know how.
We’re going to do 22 x 15 as an example. Firstly, we draw out a grid like this (you can add extra boxes at the end if you’re multiplying by 100 or 1000):
So the first multiplication we need to do is 20 x 10, which is 200.
The next multiplication we need to do is 10 x 2, which is 20.
Next, we do 20 x 5, which is 100.
Finally, we do 5 x 2, which is 10.
We then add them together using the column method, which gets us 2130.
