Mathematics - Integers - Adding and subtracting integers - Integer Addition/Subtraction Rules

6 steps: (1) Same signs → ADD absolute values, keep the sign. (-5)+(-3)=-8. (2) Different signs → SUBTRACT absolute values, take sign of the BIGGER number. (-7)+4=-3 (7-4=3, and 7 is bigger so negative). (3) Subtracting → add the opposite. 5-8 = 5+(-8) = -3. (4) Subtracting a negative → add a positi
