Subtracting Integers
Warm-Up Yesterday we talked about the integer rules. How does this chart apply to the rules? + Same - Different
Additive Inverse The additive inverse allows us to easily solve subtraction problems. This is done by adding the opposite of what is being subtracted. El inverso aditivo nos permite resolver fácilmente los problemas de resta. Esto se hace mediante la adición de lo contrario de lo que se va a restar.
