¿LO OLVIDASTE?... ES HORA DE RECORDARLO
- Additive Identity
a + 0 = a - Additive Inverse
a + (-a) = 0 - Associative of Addition
(a + b) + c = a + (b + c) - Commutative of Addition
a + b = b + a - Definition of Subtraction
a - b = a + (-b) - Multiplicative Identity
a * 1 = a - Multiplicative Inverse
a * (1/a) = 1 (siendo a diferente de 0) - Multiplication times 0
a * 0 = 0 - Associative of Multiplication
(a * b) * c = a * (b * c) - Commutative of Multiplication
a * b = b * a - Distributive Law
a(b + c) = ab + ac - Definition of Division
a / b = a(1/b)
