Chapter 5.3 PROPERTIES of Operations

Good Evening to all,

Today we are moving onward with using the PROPERTIES- properties are laws that we can use to solve math problems. They involve the operations in math ( + - x /). In these cases they really only involve multiplying and adding operations! We have the Commutative Property for x + and the

Associative Property for x +. Commutative Property is that you can switch the TERMS in an equation to solve for x +.

Example: 5 + 6 = 6 + 5 or 6(5) = (6)5 - so here the

terms or numbers are switching.

Associative Property is where the TERMS stay put,

but the Parenthesis CHANGE.

Example: (6 + 5) + 7 = 6 + ( 5 + 7).

The terms stay put and the ( ) move.

NOW this is true for x + only when you have

all the same operation!

Are these properties true for DIVIDING and SUBTRACTING? Follow along in the book and do the examples in the videos in your Reference Spirals. VOCABULARY is important again in this section, so start to use it to make sense of it.
