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)
Multiplying Integers
(+) x (+) = (+) (multiply the absolute values)
(-) x (-) = (+) (multiply the absolute values)
(+) x (-) = (-) (multiply the absolute values)
(-) x (+) = (-) (multiply the absolute values)
Dividing Integers
(+) / (+) = (+) (divide the absolute values)
(-) / (-) = (+) (divide the absolute values)
(+) / (-) = (-) (divide the absolute values)
(-) / (+) = (-) (divide the absolute values)
