Add the magnitudes, keep the sign.
You simply add the numbers: the answer has a positive sign.
Because that is how the opposite of a number is defined.
Add their magnitudes, and keep the same sign for the sum.
yes.
Add the magnitudes of the integers (-4 has a magnitude of 4), then take the sign to the answer.
Add the magnitudes, keep the sign.
copy the sign then add :)

ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.
If you mean integers, well if you have two integers of the same sign that you are adding, add and the sign stays the same. If you have different signs, subtract and keep the sign of the one that has more. Regular numbers you just add them.
yes.
to subtract an integer, add its opposite or additive inverse.
-- If they both start out with the same sign (both negative or both positive), then do this: . . . . . add their two values . . . . . the answer has the same sign as the two original integers. -- If they start out with opposite signs (one negative and one positive), then do this: . . . . . forget about the signs . . . . . find their difference (subtract the smaller number from the larger one) . . . . . give it the sign of whichever original integer was the larger number.
NO, 8 and 4 cannot be opposite integers.Integers can be opposite by the difference in sign conversion of the same number. 8 and -8 are opposite.
