HW 8.04 – ADDITION & SUBTRACTION WITH INTEGERS If you have a subtraction problem, please rewrite it as an addition problem 1. 30 +(−33) = ___________ 2. 35−(−5) = (rewrite) 3 + 8 = ___________ 3. (−26)−(−39) = (rewrite) ______________________= ___________ 4. (−29) +(−45) = ___________ 5. 30 – 38 = (rewrite) ______________________ = ___________ Now you decide when to rewrite! 6. 34 +(−37) = _____________________________________________________ 7. (−25) +(−32) = _____________________________________________________ 8. (−33)−(−34) = _____________________________________________________ 9.
