Algebraic Expression
A mathematical phrase involving at least one variable and sometimes numbers and operation symbols.
Commutative Property
3+4+5= 4+3+5
move numbers around and they mean the same thing *THINK COMMUTE = move
Associative Property
Changing the grouping of numbers will NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication
Identity Property
The property that states that the product/sum of 1/0 and any number is that number
Distribution property
a(b+c)=ab+ac a(b-c)=ab-ac
Perimeter
The distance around a figure
Area
Length x Width
Factoring GCF of 12 and 18
Length = 4
Width = x+9
Example of Factoring
6x - 13
2 + 3(2x- 5)
Answer 5x+15
5((1)+ 15=20
5(2) + 15 = 25
5(3) + 15 = 30
5(4) + 15 = 35
5(5) + 15 = 40
