In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it.
The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The property holds for Addition and Multiplication, but not for subtraction and division.
Commutative Laws. The "Commutative Laws" say we can swap numbers over and still get the same answer ... ... when we add: a + b = b + a. Example: ... or when we multiply: a × b = b × a. Example: Percentages too! Because a × b = b × a it is also true that: a% of b = b% of a. Example: what is 8% of 50 ? 8% of 50 = 50% of 8. = 4.
The associative, commutative, and distributive properties of algebra are the properties most often used to simplify algebraic expressions. You will want to have a good understanding of these properties to make the problems in algebra easier to solve.
The commutative property lets us regroup and create friendlier numbers. 10 \times 8 is easier to solve mentally than 2 \times 8 \times 5=16 \times 5. The commutative property can also be referred to as the commutative property of addition and the commutative property of multiplication, or more generally as the commutative law.
Definition: Commutative Properties. Commutative Property of Addition: if a and b are real numbers, then a + b = b + a. Commutative Property of Multiplication: if a and b are real numbers, then a • b = b • a
