How can I multiply a group of numbers?
There are two different ways to multiply a group of numbers by another number.
You could multiply each number separately and then add them together
Or you could add the numbers together first and then multiply.
Example
How much is two groups of three and two groups of four put together?
You can do this as 2 x 3 = 6 and 2 x 4 = 8.
Then add these together.
6 + 8 = 14
You can also do this by adding first. 3 + 4 = 7.
Then multiply 2 x 7 = 14
The answer is the same, so use whichever way seems better for you.
