Answer:
Commutative Property of Addition
Explanation:
Commutative property is a property that describes an expression when you can rearrange numbers in any way but still get the same sum
Example
a + b = b + a
In the above example a + b, no matter how you rearrange each letter you will still get the same sum.
Another Example
a + b + c = c + b + a
Same thing in the second example, no matter how you rearrange the letter you will end up with the same sum.
