If the signs are different, multiply or divide, the answer is always negative.Įxample: -25 ÷ 5 = -5 Thus, we have learned to add, subtract, multiply and divide positive and negative numbers. If the signs are the same, multiply or divide and the answer is always positive. Examples Same signs give a positive: 3 + ( + 2 ) 3 + 2 5 Same signs give a positive: 3 ( 2 ) 3 + 2 5 Different signs give a negative: 3 + (. = (-7) + (-2) = -7 - 2 = -9 Multiplying and Dividing Integers Rule: (-) - (+) = Change the sign of the number to be subtracted and add them up.(+) - (-) = Change the sign of the number to be subtracted and add them up.(-) - (-) = Change the sign of the number to be subtracted and add them up.The result takes the sign of the greater number.(+) - (+) = Change the sign of the number to be subtracted and add them up.The result takes the sign of the greater number.Add the two numbers and put negative in front of it. When adding a negative and a positive integer together, subtract the integers. Adding two negative numbers yields a negative number. Negative integers have rules for performing different calculations. To subtract a number from another number, the sign of the number (which is to be subtracted) should be changed and then this number with the changed sign, should be added to the first number. Here are some rules for adding and subtracting negative numbers: Adding two positive numbers yields a positive number. (‐) + (+) = subtract the numbers and take the sign of the bigger numberĮxample: (-9) + 6 = -3 Subtracting Integers Rule:.(+) + (‐) = subtract the numbers and take the sign of the bigger number.If the signs are different, subtract the numbers and use the sign of the larger number Rule 2: The quotient of two negative integers will always be positive. Rule 1: The quotient of two positive integers will always be positive. (‐) + (‐) = add the numbers and the answer is negative But the rules for division of integers are same as multiplication rules.Though, it is not always necessary that the quotient will always be an integer.(+) + (+) = add the numbers and the answer is positive.If the signs are the same, add and keep the same sign. Answer: Let's take some examples and understand the positive and negative rules for addition, subtraction, multiplication, and division as described below.īelow are positive and negative rules for addition, subtraction, multiplication, and division. We will be using the concept of integers to understand the positive and negative rules for addition, subtraction, multiplication, and division. List the positive and negative rules for addition, subtraction, multiplication, and division.
