看下面,这些题该怎么做,要用简便方法计算
3.27×6.43+3.27+3.27×2.57
  0.956+2.16-1.176-0.75 0.3-15×(8.4-5.86)÷0.01
  (6.1-4.6)×(9-0.4)+(4.1-2.85) 1-[10-(69.696÷3.2)]×1.01

3.27×6.43+3.27+3.27×2.57=3.27*(6.43+1+2.57)=3.27*10=32.7 0.956+2.16-1.176-0.75 =(0.956-0.75) +2.16-1.176=0.206+ 2.16-1.176=2.222-1.176=1.046 0.3-15×(8.4-5.86)÷0.01=0.3-1500*2.54=0.3-3810=-3...
