Three plus five plus one equals what.

When were adding three numbers together, we can add them in any order. Lets start by adding together five and one. One more than five is six. Weve added our five and our one. Now, all we need to add is the three. Six and three is nine. If we start at five and add one more, we have a total of six. Then, all we have to do is add the three to six. Three more than six is nine.

We could also start at three, add five to take us to eight. Eight add one is nine. It doesnt matter which way we add the numbers; the total is nine.
