You might think that you would subtract but you are really just trying to find the space between them. Think of a thermometer and draw one if it helps. Mark 90 °F about where it would be and then mark -2°F remembering to put it below 0. Now find the distance between them by adding. The distance between 90 and -2 is 92.
