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.
