〖1/1算式〗
    作业：求算式 (0.6*1.65+0.6*1.8)*2+(0.2*1.1+1.53*3.6)*3+(0.15*2.25+1.6*3.6)*3+2.8*3.6*3 的值.
    题型：数学计算
    解:
          (0.6*1.65+0.6*1.8)*2+(0.2*1.1+1.53*3.6)*3+(0.15*2.25+1.6*3.6)*3+2.8*3.6*3
        =2.07*2+(0.2*1.1+1.53*3.6)*3+(0.15*2.25+1.6*3.6)*3+2.8*3.6*3
        =2.07*2+5.728*3+(0.15*2.25+1.6*3.6)*3+2.8*3.6*3
        =2.07*2+5.728*3+6.0975*3+2.8*3.6*3
        =4.14+5.728*3+6.0975*3+2.8*3.6*3
        =4.14+17.184+6.0975*3+2.8*3.6*3
        =4.14+17.184+18.2925+2.8*3.6*3
        =4.14+17.184+18.2925+10.08*3
        =4.14+17.184+18.2925+30.24
        =21.324+18.2925+30.24
        =39.6165+30.24
        =69.8565
    答案:(0.6*1.65+0.6*1.8)*2+(0.2*1.1+1.53*3.6)*3+(0.15*2.25+1.6*3.6)*3+2.8*3.6*3=69.8565
