### 7.2 Commutative and Associative Properties - Prealgebra 2e

The commutative and associative properties can make it easier to evaluate some algebraic eions. Since order does not matter when adding or multiplying three or more terms, we can rearrange and re-group terms to make our work easier, as the next several examples illustrate. Example 7.8 Evaluate each eion when x = 7 8. Associative, Distributive and Commutative Properties Sep 03, 2012 · Associative property:Associative law states that the order of grouping the numbers does not matter. This law holds for addition and multiplication but it doesnt hold for subtraction and division. This can be observed from the following examples.

### Basic Number Properties Commutative, Associative and

12 + 4 = 4 + 12. -1 + 8 = 8 + -1. All the above illustrates the commutative property of addition. This means that when adding two numbers, the order in which the two numbers are added does not change the sum. All three examples given above will yield the same answer when the left and right side of the equation are added. Commutative, Associative and Distributive Laws - Math is FunCommutative Laws:a + b = b + a a × b = b × a:Associative Laws:(a + b) + c = a + (b + c) (a × b) × c = a × (b × c) Distributive Law:a × (b + c) = a × b + a × c Math Properties (Associative Identity Distributive The Associative Property, Distributive Property, Commutative Property and Identity Property are so important when first learning algebra and creating equivalent eions and combining like terms. This activity works great in small groups or partners. It is also a great resource as a scaffold for English Language learners and/or special education.

Properties of Addition - AAA MathFeedback. Properties of Addition. There are four mathematical properties which involve addition. The properties are the commutative, associative, additive identity and distributive properties. Commutative property:When two numbers are added, the sum is the same regardless of the order of the addends. For example 4 + 2 = 2 + 4.

### Use the Commutative and Associative Properties

Definition:Commutative Properties. Commutative Property of Addition:if a a and b b are real numbers, then. a + b = b + a a + b = b + a. Commutative Property of Multiplication:if a a and b b are real numbers, then. a b = b a a · b = b · a.The Commutative and Associative Properties and Algebraic Sep 15, 2013 · In summary, the commutative property states that order doesn't matter when you are performing only addition or only multiplication. a + b = b + a and ab = ba . Your terms can commute
