Explain it: write the definition and give an example of the commutative property of addition using decimal numbers

The Commutative Property of Addition states that when finding a sum, changing the order of the addends will not change their sum. In symbols, the commutative property of addition says that for numbers a and b: a+b=b+a

Here is an example using simple whole numbers.
Show that 2+4=4+2.

First, find 2+4. 2+4=6

Next, find 4+2. 4+2=6

Notice that both sums are 6.
