Example Question #21 : Understand Distances Between Numbers On A Number Line: Ccss.Math.Content.7.Ns.A.1b
Use the number line provided to help solve the following problem:
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.
