Definitions:

Same Sign - Add the absolute values and give the answer the same sign.

Different Signs - Subtract the smaller absolute value from the larger absolute value and give the answer the same sign as the number with the larger absolute value

Subtracting Integers - Same as adding the opposite of that integer number.

A general example to help you recognize patterns and spot the information you're looking for

Adding Integers $$(-3) + 2 = -1$$ $$21 + (-28) = -7$$ $$9 + (-9) = 0$$ Subtracting Integers $$−3 − (−9) = −3 + 9 = 6$$ $$−7 − 8 = −7 + (−8) = −15$$

We use these operations every day.
