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
A negative or a positive! It depends on the question.EXAMPLES-7 + 3 = -4 ( a negative answer)-7 + 8 = 1 (a positive answer)IF you mean a negative times a positive, the answer is negative:-3 x 5 = -15

The following are factors of 750, meaning they go into 750 a certain number of times. To find out how many times the number goes into 750, find the corresponding number on the other side of the array. For instance to see how many times 5 goes into 750, find the 4th-last number in the array (150):1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750

A negative number. Ie; -5 x 3 = -15
A negative times a negative is a positive (-4)(-5) = positive 20
