#### Answer:

It is an example of at least two algebraic properties:

Commutativity and associativity.

#### Explanation:

Addition is:

Commutative:#A+B = B+A#

Associative:#(A+B)+C = A+(B+C)#

The example *commutativity* to get

The example also uses *associativity* to even write

The example also expresses *equality*, which might also be counted as an algebraic property, but is often just assumed.
