Rules for Adding and Subtracting Integers


Adding Integers
(+) + (+) = positive (add the absolute values)
(-) + (-) = negative (add the absolute values)
(+) + (-) = ? (subtract the absolute values)
(-) + (+) = ? (subtract the absolute values)

Note: (+) means positive, (-) means negative, and (?) represents the sign of the greatest number in absolute value


Subtracting Integers
(+) - (+) = (+) + (-)= ? (subtract the absolute values)
(-) - (-) = (-) + (+)= ? (subtract the absolute values)
(+) - (-) = (+) + (+)= (+) (add the absolute values)
(-) - (+) = (-) + (-)= (-) (add the absolute values)
