commutative property of addition

a+b=b+a

commutative property of multiplication

ab=ba

associative property of addition

a+(b+c)=(a+b)+c

associative property of multiplication

a(bc)=(ab)c

distributive

a(b+c)=ab+ac

multiplicitave inverse

a --> 1/a (reciprocal)

additive inverse

a --> -a

multiplicitive identity

1 ex: 3•1=3

additive identity

0 ex: 3•0=0

universe

all the elements in the given problem

set

a collection of elements from the universe use these { }

intersection

upside down U elements in common

union

U includes all elements from each set NO REPEATS IN # ORDER!

complement

("not") elements from the universe that are not in the set

THE END

ALL DONE!!
