9.3.1: Associative, Commutative, and Distributive Properties

WebFeb 14, 2024 · The Commutative Property has to do with order. We subtract \(9−8\) and \(8−9\), and see that \(9−8\neq 8−9\). Since changing the order of the subtraction does not give the same result, we know that subtraction is not commutative. Division is not commutative either. Since \(12÷3\neq 3÷12\), changing the order of the division did not ... WebThe commutative property of multiplication states that when two numbers are being multiplied, their order can be changed without affecting the product. For example, 7 · 12 has the same product as 12 · 7. 7 · 12 = 84 12 · 7 = 84 These properties apply to all real numbers. Let’s take a look at a few addition examples. Subtraction is not commutative. In group and set theory, many algebraic structures are called commutative when certain operands satisfy the commutative property. In higher branches of mathematics, such as analysis and linear algebra the commutativity of well-known operations (such as addition and multiplication on real and … See more 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. Most … See more Records of the implicit use of the commutative property go back to ancient times.
