2-24 But a negative minus plus a positive plus can be minus, zero or plus: For example, -3 + 2 -1 -3 + 3 0 -3 + 4 +1. An odd number of negative numbers will give a negative answer. -1+-1-2 Negative times a negative is a positive.
#NEGATIVE PLUS NEGATIVE POSITIVE OR NEGATIVE HOW TO#
Today, we are going to learn how to multiply and divide by. The rule works the same way when you have more than 2 numbers to divide or multiply. Hello, In our last post, we discussed how to add and subtract positive and negative integers. To get a negative number, you need 1 positive & 1 negative number. You cannot multiply a number by itself to get a negative number. (negative number) × (positive number) = negative number (positive number) × (positive number) = positive number Adding a positive and a negative could yield either a positive or a negative number, depending on the values of the numbers being added.
5+-2-7 but if you are subtracting a negative number from a negative, then the second negative number would become a positive. Adding a negative number to a positive is essentially just subtraction. Thats just the way that things are in twos complement: a leading 1 means the number is negative, a leading 0 means the number is 0 or positive. (negative number) × (negative number) = positive number A negative plus a negative is positive No a negative plus a negative is not a positive answer. (Just change the positive + sign to the negative - sign). For another example if the problem was -6 + 10, Since 10 is the greater number your answer will be positive. 0 is neither a positive nor negative number. When the signs of the 2 numbers are the same, the answer will be positive. Since the numbers are equal it becomes neither. When the signs of the 2 numbers are different, the answer will be negative. Two Negatives make a Positive Multiplying & Dividing Positive & Negative Numbersįirst, ignore the signs, multiply or divide the numbers as if they were both positive.Īfter you have the numerical answer, apply a very simple rule to decide the sign of the answer: Subtracting a Negative is the same as adding!
