operation signs, andsometimes variables

thatnames a number, with

an = sign

algebra5

a type of math that usesletters or other symbolsto represent numbers

inequalities6

statements indicating that twoquantities are not equal,

utilizing symbols > (greater than)

or < (less than) or =

variable7

a symbol used to represent a number

A + 6 = 9

compute8

solve, to determine ananswer by mathematicalprocedures

distributive property9

The property that states that multiplying a sum by a number gives the same result as multiplying by each number then adding the products

3(5+6) = (3x5) + (3x6)

associative property

10

in addition and multiplication,changing the order of the grouping does not change the sum or product

(4 x 6) x9 = 4 x (6 x 9)

commutative property

11

a property of addition and multiplication that states that by changing the order of addends or factors doesnot change the sum or product

5 + 8 = 8 + 5

identity property12

the property that statesthat by adding 0 or by multiplying by 1 does not change a number

a + 0 = a a x 1 = a

inverse property13

The property that states:the sum of a number andits opposite is 0

9 + (-9) = 0

parentheses14
