Exactly, it’s just the commutative and associative properties!

In this article I’m talking about elementary school math and they don’t tend to introduce those laws formally until pre-algebra, so I didn’t mention it. In my mental math articles geared for adults on addition and subtraction, I talk more about the laws of math that allow us to do these tricks.

**Learning how to use these properties with numbers can help reinforce this topic when they attempt the same properties in algebra.**

As student move up towards middle and high school math they are slowly introduced to mathematical notation preparing them for, if they choose, advanced mathematics.
