To add two integers with opposite signs . . .

-- Ignore the signs, and write the difference between the two numbers.

-- Give it the same sign as the larger original number has.

## Related Questions Add the magnitudes of the integers (-4 has a magnitude of 4), then take the sign to the answer.     Add their magnitudes, and keep the same sign for the sum. 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. additionslike sign -just add and copy the sign of the integersunlike signsubtract the integers then copy the sign of the bigger integers.subtractionchange the sign of the subtrahend and proceed as in adding integers.multiplication and Divisionwith like signsthe product or quotient is positiveunlike signthe product or quotient is negativeby:jen Marie :) 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.  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. Just multiply without the sign. Then add a minus sign to the result. Two integerss add to zero when their absolute values are equal and they have opposite signs. If the larger of the two integers is negative, then their sum is negative, regardless of the sign of the smaller one. Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.   -- 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. To add integers with like signs you jut put the positive in front of the answer (you just add and put a positive sign in front of it)  Integers are the "counting numbers" and their negative counterparts, and zero. Opposite integers are the pairs of integers that have the same absolute value, or, in other words, are the same distance from zero. 10 and -10 are opposite integers. 43 and -43 are opposite integers. It's just that simple. Add the numerals and keep the sign. Examples: +9 + +3 = +12 -5 + -6 = -11 Just in case this is your next question: to add integers with different signs, subtract the numerals, and use the sign of the larger number. To add two integers with unlike signs: -- Find the difference between their sizes, ignoring their signs. -- Give the difference the sign of the integer with the larger size. if they are both negative, add like they are positive numbers, but just add the negative sign. You simplyadd them and keep the same sign. 3 + 2 = 5 -3-2 = -5
