### Example Question #1 : Add And Subtract Rational Numbers: Ccss.Math.Content.7.Ns.A.1d

Solve:

**Possible Answers:**

**Correct answer:**

Let's work from left to right since it's only subtraction and addition. Since is greater than and it's positive our answer is positive, but we treat this like a subtraction problem because the is negative. . Now we have . is greater than and it's negative so our answer is negative and we treat this like a subtraction problem. , but since our answer should be negative our answer is .

### Example Question #1 : Add And Subtract Rational Numbers: Ccss.Math.Content.7.Ns.A.1d

Use the number line provided to help solve the following problem:

**Possible Answers:**

**Correct answer:**

In order to solve this problem, we need to start at on the number line.

Next, we have which means we need to move places to the right on the number line. When we have an addition sign we move to the right because that is towards the positive side of the number line. When we have a subtraction sign we move to the left because that is towards the negative side of the number line.
