If you’re still confused over why a negative number times a negative number makes a positive number, Diana Brown at the Department of Mathematics, the University of Georgia, explains it in many different ways in this article. Here’s the overall rule to remember when multiplying positive and negative numbers: 2 x -4 are both negative, so we know the answer is going to be positive. If the coefficient is negative, now the end behavior on both sides will be. If the value of the coefficient of the term with the greatest degree is positive then that means that the end behavior to on both sides. Rules for the addition of positive and negative integers To add two positive integers or two negative integers, we add their absolute values and assign the sign of the addends. If you look at it on the number line, walking backwards while facing in the negative direction, you move in the positive direction.įor example. All polynomials with even degrees will have a the same end behavior as x approaches - and. rules for multiplying and dividing integers: V (negative) × (negative) positive V (negative) + (negative) positive V (negative) x (positive) negative V (. Two negatives make a positive, so a negative number times a negative number makes a positive number.
Rule 3: A negative number times a negative number, equals a positive number. It doesn’t matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.įor example: -2 x 4, which in essence is the same as -2 + (-2) + (-2) + (-2)Īnd as we said, if it’s the other way around 4 x -2, the answer is still the same: -8. When you multiply a negative number to a positive number, your answer is a negative number. Rule 2: A negative number times a positive number equals a negative number. 5 is a positive number, 3 is a positive number and multiplying equals a positive number: 15. Skill Icon B.21Integer multiplication and division rules Skill Icon B.21. If one is positive and the other negative, the answer will be. This is the multiplication you have been doing all along, positive numbers times positive numbers equal positive numbers.įor example, 5 x 3 = 15. When multiplying (or dividing) two numbers with the same signs, the resulting answer is positive. There are only three rules to remember: Rule 1: A positive number times a positive number equals a positive number. The negative sign is used at the beginning of something new, so it could be primarily in three places -3(-4 + x)/-6. There are less rules when multiplying positive and negative numbers than in adding and subtracting positive and negative numbers. (-5) + (-3) (-8) (Basically add the numbers and put back the negative sign) Sum of a negative and positive number: Subtract the smaller number from the larger number and put back the sign of the larger number.
