The Commutative Property of equality states that when multiplying two or more numbers, it does not matter which is first or second, as the product (answer) always remains the same.
a * b = b * a
Example 1: 3 x 7 = 21 and 7 x 3 = 21
Example 1:
3 x 7 =
21
and
7 x 3 = 21
Example 2: 4 x 5 = 20 and 5 x 4 = 20
Example 2:
4 x 5 =
20
and
5 x 4 = 20
The Associative Property of equality states that numbers can be grouped in any combination to arrive at the same product (answer).
a * (b * c) = (a * b) * c
Example:
2 x (4 x 5) = 40 = (2 x 4) x 5
2 x (20) = 40 = (8) x 5
Example:
2 x (4 x 5) =
40
(2 x 4) x 5 = 40
The Identity Property of equality states that the product of any number and 1 is itself.
a * 1 = 1
Example: 9 x 1 = 9
The Zero Property of equality states that the product of any number and zero is 0.
a * 0 = 0
Example: 8 x 0 = 0
