Commutative property why

As with the commutative property , addition and multiplication are associative operations: The distributive property can be used when the sum of two quantities is then multiplied by a third quantity. Adding and Subtracting Polynomials When adding polynomials, the commutative property allows us to rearrange the terms to group like terms together. Multiplying Polynomials Multiplying a polynomial by a monomial is a direct application of the distributive and associative properties.

Explain how to multiply polynomials using the distributive property and describe the results of doing so Adding and Subtracting Algebraic Expressions The Commutative Property of Addition says that we can change the order of the terms without changing the sum.

Commutative Addition While we can look at equations all day, I want to feature some mouth-watering examples that highlight these facts when talking about food. Commutative Multiplication Now we're going to show why multiplication is commutative by figuring out how many ways to make a sandwich.

Let's say that a sandwich has three components: bread, cheese, and meat. We'll use this fact to make it clear that multiplication is commutative. Let's say you want to choose one of each to build a sandwich for lunch. Related Lessons. View All Related Lessons.
