2. A set of steps leads down into a swimming pool. Some of the steps are above the water level and some of the steps are below the water level. The top of one of the steps is even with the water level of the pool. Each step is 8 inches tall. Positions below the water level are represented as negative values and positions above the water level are represented as positive values. Kevin's feet are on the step that is even with the water level of the pool. Kevin then moves to a new position on the steps. The product represents the new position of Kevin's feet. (a) Explain what the product means in terms of how Kevin moved on the steps. (b) Calculate the product to determine the new position of Kevin's feet.
