Switch & Not
Biconditional
If and only if
if a = b, then a + c = b+ c
Addition PoE
if a = b, then a - c = b -c
Subtraction PoE
if a = b, then c x a = c x b
Multiplication PoE
If a = b, then a/c = b/c
Division PoE
a=a or ab = ab
Reflexive Property
If a and b are real numbers and a = b, then a can be substituted for b
Substitution Property
If a = b and b = c, then a = c
Transitive Property
a(b + c) = ab + ac
Distributive Property
If 2=x then x= 2, and if 7 = ab then ab = 7
Symmetric Property
