(PEMDAS) Mathematical statements that are true of any number belonging to the set of numbers for which the properties are defined. Variable - A letter or symbol used to represent an unknown number.

13. Properties Commutative- states that the order in which numbers are added or multiplied does not change the sum or product. Ex: 4+3=7 or 3+4=7 Associative- states that the way in which numbers are grouped does not change the sum or product. Ex: 1 + (2+3) = 6 or (1+2) +3= 6 Identity- states that any number added to 0 or multiplied by 1 will be itself. Ex: 6 + 0 = 6 or 4 x 1 = 4 Distributive- is used to simplify or rewrite expressions by multiplying a number outside the parenthesis by each number or term inside the parenthesis. Ex: 4(2 + 3) = 8 +12

19. I Can…. Apply the properties of operations to generate equivalent expressions.

20. Algebraic Properties Essential Understanding: Algebraic properties can be used to rewrite expressions or generate equivalent expressions. For instance, the expression 3+4+2 can be rewritten like this 4+3+2 using commutative property of addition to rearrange the numbers. Examples of other algebraic properties: I.1 x 4 x 3 = 4 x 3 x 1 II.(6 + 3) +8 = (8 +3) + 6 III.9 x (3 x 2) = (9 x 3) x 2 IV.4(3 – 2)

29. I Can…. Apply the properties of operations to simplify expressions.

30. Distributive Property Essential Understanding: Distributive property can be used to rewrite algebraic expressions by multiplying the number outside the parenthesis by each number, term, or variable inside. For instance the expression 3(p+2) can be rewritten as 3p + 6 Examples: I.2(3+7) II.(6-3)3 III.5(3+6d) IV.(4-a)8 V.(5b+6c)8 VI.9(ab + 4c)
