Conditional Statement

If p then q

Negation

The opposite of what the conditional statement is, not P

Inverse

Negate both they hypo. and conc. if not P then not Q

Converse

Contrapositive

If not q then not P write the converse then negate the hyp. and conc.

Biconditional Stament

P if and only Q, write a conditional statement and its converse is true

Addition Property of Equality

if a=b then a+c=b+c

Subtraction Property of Equality

if a=b then a-c=b-c

Multiplication Property of Equality
