![]() What does a positive and a negative equal? 3 What is a positive plus a positive equal?.2 Why do negatives cancel out in multiplication?.1 What does a positive and a negative equal?.These examples use integers and whole numbers, but the same rules apply to decimals and fractions. Any number divided by zero is infinity. ![]() Multiplying any number (positive or negative) by zero gives an answer of 0.If there are an odd number of negative signs, the answer is negative. If there is an even number, the answer is even. When multiplying or dividing several numbers, add up the number of negative signs.If one number is positive and the other is negative, the result is negative.(Basically, the two negative values cancel each other out). If both numbers are negative, the result is positive.If both numbers are positive, the result is positive.The rules for multiplication and division are simple: Multiplying or dividing positive and negative numbers gives a negative number. Multiplication and Division of Positive and Negative Numbers If you multiply or divide like signs, you get a positive number. The answer has the sign of the larger number. When you subtract a negative number from another negative number, once again the negative signs cancel each other to become a plus sign. It makes the positive number more positive. Subtracting a negative number from a positive number cancels out the negative signs and becomes simple addition. In other words, it makes the negative number more negative. When you subtract a positive number from a negative number, it’s the same as adding a negative number. If you subtract a large positive number from a smaller positive number, you get a negative number.Īn easy way to do this is to subtract the smaller number from the larger number and change the sign of the answer to a minus. For two positive numbers, if the first number is larger than the second, then the result is another positive number. The rules for subtraction are similar to those of addition. For example:įind the sum of a positive and negative number by subtracting the number with the smaller value from the one with the larger value. Simply find the sum of the numbers and keep the sign. Addition and Subtraction of Positive and Negative Numbers When you add or subtract positive and negative numbers, the sign of the answer depends on whether the signs are alike or which number has a larger value.Īdding positive and negative numbers is simple when both numbers have the same sign. Number lines can make positive and numbers easier to understand, too. Generally, it’s easier to perform operations on negative numbers if they are enclosed in brackets to keep them separate. There are rules for adding, subtracting, multiplying, and dividing positive and negative numbers. Zero is neither a positive nor negative number. ![]() The sum of a positive number and its equal negative number is zero. ![]() Its sign is considered to be negative and it is written with a minus sign in front of it (e.g., -2, -23).
