  42*3 - 35*2 ＝56
2.在一个长11 meters，宽6 meters的房间里，铺上10 centimeters厚的水泥，问需要多

少水泥？
  11*6*0.1＝6.6 cubic meters
3.某公司有两座办公楼，一天，第一座楼20％的复印机和第二座楼40％的复印机需要进
行维护，如果第一座楼拥有公司60％的复印机，问这天在维护的复印机是多少？
   20% * 60% + 40% * (1 - 60%) = 28%

走12公里。现在要开15000公里，其中有60％由van来承担，问更新后将节省多少油？
  (15000 * 60% / 12 + 15000 * 40% / 15) - (15000 * 60% / 15 + 15000 * 40% / 
20) = 250
