1.4: Commutative Property of Addition and Multiplication
In addition to knowing the order of operations, we need to understand some properties of arithmetic before we can begin evaluating more complicated algebraic expressions.
The commutative property of addition and multiplication states that the order
of the input numbers does not matter. For example, 3 + 2 = 5 and 2 + 3 = 5. Likewise, 3 × 2 = 6 and 2 × 3 = 6.
Watch these videos for examples of how to apply these laws in arithmetic.
