Properties

Commutative Associative Identity of Addition Identity of Multiplication Zero property

Commutative

1+4=4+1 5*4=4*5

*Note, Allows us to add or multiply in any order

Associative

(2+6)+4=2+(6+4) 2*(3*4)=(2*3)*4

Allows us group numbers without changing the order

Identity of Additions

5.6+0=5.6

It always is going the same number

Identity of Multiplication

5*1=5

Always the same number on the other side of the =

Zero Property

5*0=0

Always going to equal 0

Prime Numbers

A number that only has 2 factors, 1 and its self

Ex: 2,3,5,7,11

Zero and one r neither composite or prime

Composite Numbers

A number that has more than 2 factors Ex: 4,6,8,9,10
