Evaluate w – d if d = –2 and w = 3.

Describe how to use absolute value to find the distance between -10 and 5 on a number line. Then use this method to determine the distance between the integers.

• You subtract the two integers (-10 - 5 = -15), then take the absolute value of -15, which is 15. So the distance is 15.

• You subtract the two integers (-10 - 5 = -15), so the distance is -15.

• You add the two integers (-10 + 5 = -5), then take the absolute value of -5, which is 5. So the distance is 5.

• You add the two integers (-10 + 5 = -5), so the distance is -5.
