I. Addition 1. Positive + Positive = Positive ( +3 PLUS +3 = +6) 2. Negative + Negative = Negative (-3 PLUS -3 = -6) 3. Positive + Negative OR Negative + Positive Subtract the numbers then copy the sign of the number with greater value. (+5 PLUS -3 = +2) (-5 PLUS +3 = -2) II. Subtraction Change the sign of the subtrahend then the follow the rules of addition above. Examples: +5 MINUS -3 = +5 +3 = +8 +5 MINUS +3 = +5 -3 = +2 III. Multiplication 1. Positive x Positive = Positive (+3 times +5= +15) 2. Negative x Negative = Positive (-3 times -5 = +15) 3. Positive x Negative = Negative (+3 times -5 = -15) 4. Negative x Positive = Negative (-3 times +5 = -15) IV. Division Same rules as in multiplication Note: Like signs when multiplied or divided together = Positive Unlike signs when multiplied or divided together = Negative
