Think
Describe
When you add and it
keeps the nuber the
same .
identity is 0
What you multiply by a
number so it keeps its
identity.
multiplicative identity is 1
When you add a
number to its inverse it
equals 0
When you multiply a
number by its inverse it
equals 1
Example
5+0=5
5x1=5
3 + (-3) = 0
Property:

Describe
Commutative
Property
Add or
multiple in
any order
Associative
Property
When adding
or multiplying,
you can group
in any order
Distributive
Property
Example
5+2 = 2+5
5x2 = 2x5
2(3+4) = 2(3) + 2(4)
a(b + c) = ab + ac
