Jack goes up three flights of stairs, then down six flights of stairs. If each flight of stairs has 12 steps that each each 8 inches high, how many feet further down is Jack than when he started?
First find the number of inches in each flight of stairs: 12 steps * 8 inches/step = 
<gadget id="calculator">12*8</gadget>
<output>96</output>
96 inches.
Then find the net number of flights of stairs Jack went down: 6 flights - 3 flights = 
<gadget id="calculator">6-3</gadget>
<output>3</output>
3 flights.
Then multiply than number by the number of inches per flight to find how many inches further down he is: 96 inches/flight * 3 flights = 
<gadget id="calculator">96*3</gadget>
<output>288</output>
288 inches.
Then divide that number by 12 to find the number of feet down he is: 288 inches / 12 inches/foot = 
<gadget id="calculator">288/12</gadget>
<output>24</output>
24 feet.
