Playing Around with Numbers

Numbers in our lives from the earliest years.

Here’s a trick for addition I learned later in life. If you have to add something to a 9 it will always be that number minus 1. Like if you were to add 4 + 9 = 13. That 4 becomes a 3. So, the end result is going to have a 3 on the end of it.

5 + 19 = 24 (The 5 became a 4)
