So to add and subtract positive and negative numbers, here is the rule to remember. If the operation and the sign are the same, they work like the addition of a positive number.
Negative Numbers: Adding & Subtracting. Rule: When you have two signs next to each other in an addition or subtraction question, you have to replace them with a single sign. The rule is: if the signs are the same, replace them with a +. if the signs are different, replace them with a −. Examples: Work out. −6 − −9 = −6 + 9 = 3.
A negative number is written with a minus sign in front. The four operations are addition (+), subtraction (–), multiplication (×) and division (÷). When adding and subtracting negative numbers, it may help to have a number line.
1 Μαΐ 2017 · Let a positive number be represented by a right-facing arrow and a negative number be represented by a left-facing. To add two integers, find the point on the number line corresponding to the first addend (integer).
Rules for Adding and Subtracting Negative Integers. 1. If both signs in the equation are negative, your answer will be negative as well. 2. If one sign is positive and one negative, subtract the smaller of the absolute value. Your answer will be the same sign as the larger number. For example, 6 + (-3) is the same as 6-3, which is 3.
Adding Integers. Rule: If the signs are the same, add and keep the same sign. (+) + (+) = add the numbers and the answer is positive (‐) + (‐) = add the numbers and the answer is negative. Rule: If the signs are different, subtract the numbers and use the sign of the larger number.
