Tricks for Adding and Subtracting Negative Numbers. Adding and subtracting numbers can be confusing at first because the idea of a negative quantity of something can be a strange concept, even to a 6th grader. Instead, introduce the concept of negative numbers using measurements that might convincingly have negative results.
on a number line. THE NUMBER LINE NEGATIVE NUMBERS POSITIVE NUMBERS Absolute Value- The distance a number is from zero on the number line. An absolute value is never negative. Examples: l-5 l = 5 and l 5 l = 5 ADDING INTEGERS SAME SIGN- Add and Keep the Sign! Add the absolute value of the numbers and

The last two examples showed us that taking away balloons (subtracting a positive) or adding weights (adding a negative) both make the basket go down. So these have the same result: (+6) − (+3) = (+3) (+6) + (−3) = (+3) In other words subtracting a positive is the same as adding a negative. Subtracting A Negative Number

The great secret to adding and subtracting negative numbers is to turn every problem into a series of ups and downs on the number line. When you know how to do this, you find that all these problems are quite simple. Don’t worry about memorizing every little bit of this procedure. Instead, just follow along […]
If you add a cold cube (add a negative number), the temperature goes down. If you remove a hot cube (subtract a positive number), the temperature goes down. And if you remove a cold cube (subtract a negative number), the temperature goes UP! That is, subtracting a negative is the same as adding a positive.
