    题型：数学计算
    解:
          1*1.5*3+1.6*1.3*2+1.2*2*3+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+(1.2*9.3+1.3*8)*2
        =1*1.5*3+1.6*1.3*2+1.2*2*3+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+21.56*2
        =1.5*3+1.6*1.3*2+1.2*2*3+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+21.56*2
        =4.5+1.6*1.3*2+1.2*2*3+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+21.56*2
        =4.5+2.08*2+1.2*2*3+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+21.56*2
        =4.5+4.16+1.2*2*3+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+21.56*2
        =4.5+4.16+2.4*3+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+21.56*2
        =4.5+4.16+7.2+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+21.56*2
        =4.5+4.16+7.2+0.38*2+1.2*2.3*2+1.3*2.5*3+21.56*2
        =4.5+4.16+7.2+0.76+1.2*2.3*2+1.3*2.5*3+21.56*2
        =4.5+4.16+7.2+0.76+2.76*2+1.3*2.5*3+21.56*2
        =4.5+4.16+7.2+0.76+5.52+1.3*2.5*3+21.56*2
        =4.5+4.16+7.2+0.76+5.52+3.25*3+21.56*2
        =4.5+4.16+7.2+0.76+5.52+9.75+21.56*2
        =4.5+4.16+7.2+0.76+5.52+9.75+43.12
        =8.66+7.2+0.76+5.52+9.75+43.12
        =15.86+0.76+5.52+9.75+43.12
        =16.62+5.52+9.75+43.12
        =22.14+9.75+43.12
        =31.89+43.12
        =75.01
    答案:1*1.5*3+1.6*1.3*2+1.2*2*3+1.9*0.2*2+1.2*2.3*2+1.3*2.5*3+(1.2*9.3+1.3*8)*2=75.01
