Real numbers: a,
b, c
1. Additive Identity
a + 0 = a
2. Additive Inverse
3. Commutative of Addition
a + b = b + a
4. Associative of Addition
(a + b) + c = a + (b + c)
5. Definition of Subtraction
a – b = a + (– b)
6. Multiplicative Identity
a ∙ 1 = a
7. Multiplicative
Inverse
8. Multiplicative
a ∙ 0 = 0
9. Commutative of Multiplication
a ∙ b = b ∙ a
10. Associative of Multiplication
(a ∙ b) ∙ c = a ∙ (b ∙ c)
11. Distributive Law
a (b + c) = ab + ac
12. Definition of Distributive
