equivelent expressions

expressions that have the same value

Reflexive Property

any quantity is equal to itself

Symmetric Property

if a=b, then b=a

Transitive Property

If a=b and b=c, then a=c

Additive identity

a + 0 = a

Additive Inverse

a + (-a) = 0

Multiplicative Identity

a x 1 = a

Multiplicative Inverse

Two numbers with a product of 1

Communative Property

Number order can be changed without changing the answer

Associative Property

The way in which numbers are grouped does not change their sum or product

Substitution Property

If a = b, then a can be substituted for b in any equation or expression

Distributive Property

a(b + c) = ab + ac
