Adding integers with the same signs: Add their absolute values and affix the sign of the two integers.
Adding integers with different signs: Subtract the absolute values of both integers. The integer with the greater absolute value will be the minuend and the other will be the subtrahend. Affix in the difference the sign of the integer with the greater absolute value.
