Learning Target:
Students will understand the different properties of real numbers to be able to simplify numerical and algebraic expressions and solve equations.
3
Commutative Property
he Commutative Property states that when adding or multiplying two or more numbers or terms, order is not important. That is:
However, subtraction and division are not commutative, as shown below.
4
Associative Property
The Associative Property states that when adding or multiplying three or more numbers or terms together, grouping is not important. That is:
However, subtraction and division are not associative, as shown below.
5
Identity Property
The Identity Property of Addition states that adding zero to any expression gives the same expression. That is:
The Identity Property of Multiplication states that multiplying any expression by one gives the same expression. That is:
