🎙️
How can we multiply 13 times 5
🎙️
Even for larger numbers, it's still equal to 13 groups with each group having 5 items in it
🎙️
But let's look at the 13 groups as being 10 groups of 5 items, and then another 3 groups of 5 items
🎙️
For the 3 groups, we can add them up individually and see that 3 groups of 5 is 15.
🎙️
Notice that we're skip counting by 5s, so let's try that 10 times to see what 10 groups of 5 is. We can see that it's 50
🎙️
So ten groups of 5 is 50, and 3 groups of 5 is 15. We need both of those for our answer.
🎙️
So we can add them together. 50 plus 15 is 65
🎙️
Which means that 13 times 5 is equal to 65.
