We've already seen how to add multiples of 10's here. Now we are going to add multiples of 100 to a single digit number.
When dealing with a multiple of one hundred we need to consider the units, tens, and hundreds place value. A multiple of 100 is going to have a value in the hundreds place, the number in the hundreds place is how many hundreds there are.
The number 400 is a multiple of 100, there are four 100s.
If we add 100 + 100 + 100 + 100 we get 400.
So to add a multiple of 100 to a single digit number we need to add each step of 100 for as many hundreds there are.
4 + 300 is the same as 4 + 100 + 100 + 100.
let's see a visual representation of this.
