So the equation turns into a simple addition problem.įor example: let’s say we have the problem 2 – (-3). So, instead of subtracting a negative, you’re adding a positive. Example: -7.29 + -3.8 -11.09 but if it was 7.29 + -3.8 the answer 11.09 would be positive because the bigger number is positive. But, a lot of people make the mistake of subtracting even though the sign is a plus. Rule 4: Subtracting a negative number from a positive number – turn the subtraction sign followed by a negative sign into a plus sign. I have done my research and I found out negative plus negative can be negative or positive depending on the bigger number. So we’re changing the two negative signs into a positive, so the equation now becomes -2 + 4.Ĭlass="green-text">The answer is -2 – (-4) = 2. This would read “negative two minus negative 4”. ![]() Basically, - (-4) becomes +4, and then you add the numbers.įor example, say we have the problem -2 - –4. So, instead of subtracting a negative, you are adding a positive. Because you are adding a negative to another negative. like this: -7 + -8 1 Because youre adding a minus It Will Not Equal a Positive it will Equal a Negative. Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. Negative plus Negative would equal positive in Maths. So keep counting back three spaces from -2 on the number line. If we combine these negative numbers with the positive ones, together we get a set of numbers which we call integers. Using the number line, let’s start at -2. Example: 5 is really +5 Play with it On the Number Line positive goes to the right and negative to the left. ![]() Rule 2: Subtracting a positive number from a negative number – start at the negative number and count backwards.įor example: Say, we have the problem -2 – 3. How to Add and Subtract Positive and Negative Numbers Numbers Can be Positive or Negative This is the Number Line: No Sign Means Positive If a number has no sign it usually means that it is a positive number. So solve this equation the way you always have: 6 – 3 = 3. 9 years ago The first negative number does not have brackets because it is easily recognized as a negative number. ![]() Rule 1: Subtracting a positive number from a positive number – it’s just normal subtraction.įor example: this is what you have learned before. Here are some simple rules to follow when subtracting negative numbers. When we subtract negative numbers or subtract negative numbers to positive numbers, it gets more complicated. Since -10 evaluates to the same as 10, absent further qualification the value 0 is in this regard equally-justifiable as negative and positive, thus considering negative numbers as belonging to (-,0 and positives to 0,), non-disjoint (the exhaustive ranges not mutually exclusive) from eachother although more-precisely.
