There are 100 balls in each bag. How many balls are there?

We can see that there are three bags of balls. And we know that each bag contains 100 balls. So to count the number of balls in the bags, we need to count in 100s. 100, 200, 300. But that isn’t the total number of balls. We have to count these ones too. They haven’t been grouped, so we can count these as ones. There are four ones. 301, 302, 303, 304. First, we counted in 100s. Then, we counted in ones. We had three 100s and four ones.

Did you notice that there were no 10s, only 100s and ones? The total number of balls is 304.
