Signed Numbers Word Problems Worksheets
How Do You Spot Negative Values in Word Problems? Rarely you get to see negative values in a word problem; however, how can you identify them if they are present? To solve this dilemma, let's consider an example and solve them accordingly. 12-year old Jake wanted to buy candy from a local store. However, he didn’t have money, so he bought candy on loan from the kind shopkeeper worth $3. The next day he wanted to buy more candies from the shopkeeper and told him that he will the coming day. So, he bought candies and soda worth $8 and left. The next day, he came by with $15 and asked the shopkeeper, "how much loan he has to pay?" In this scenario, Jake has $15; however, he already has a debt of $3 and then $8 that he has to payback. So, first of all, he’s bill is already -$11. Now, he’ll pay around $15, so that he can get a return of -$11 + $15 = $4. There are other examples that also can help in resolving negative word problems.
