Resta de números enteros

Para restar números enteros lo haremos por medio de una equivalencia. Es decir ‘’transformaremos’’ una resta a suma equivalente por medio de su inverso aditivo.

Ejemplo:

5 - (-8) = 5 + 8

Cambiamos el signo de resta por uno de suma y el sustraendo (2° números de la resta) se cambia de signo en este caso antes era NEGATIVO ahora es POSITIVO.

Identifica cada resta con la suma equivalente.
