Equations And Expression
Lesson 1 Use Addition Properties To Evaluate Expressions Commutative Property Definition: The order in which numbers are added does not affect their sum. Associative Property Definition: The way in which numbers are grouped does not affect their sum. Identity Property Definition: The sum of any number and 0 is that number.
Expression Definition: A mathematical sentence with an equal sign. Example: 3+1=4 and 2x + 5 =9 are equations Equation Definition:A number, a variable, or any combination of numbers, variables, operation signs, and grouping symbols. Variables Definition: A letter or symbol that represents a number in an algebraic expression.
Lesson 2 Use Multiplication Properties To Evaluate Expressions Associative Property Definition: Changing the grouping of factors does not change their product Commutative Property Definition: Changing the order of factors does not change their product Identity Property Definition: The product of a number and 1 is that number Zero Property Definition: The product of a number and 0 is 0
Lesson 3 Order Of Operations P . E . M . D . A . S Definition: P- Parenthesis E- Exponent M- Multiplication D- Division A- Addition S- Subtraction
Lesson 4 Use Distributive Property To Evaluate Expressions Distributive Property Definition: The property which states that when two addends are multiplied by a factor the product is the same as if each addened was multiplied by the factor and those products were added.
