    解:
          22.39*12.3+10.9*22.3-9.8*9.2-17.05*8.05-9.7*8.05-16.7*9.3+9.8*10.8+9.8*9.35
        =275.397+10.9*22.3-9.8*9.2-17.05*8.05-9.7*8.05-16.7*9.3+9.8*10.8+9.8*9.35
        =275.397+243.07-9.8*9.2-17.05*8.05-9.7*8.05-16.7*9.3+9.8*10.8+9.8*9.35
        =275.397+243.07-90.16-17.05*8.05-9.7*8.05-16.7*9.3+9.8*10.8+9.8*9.35
        =275.397+243.07-90.16-137.2525-9.7*8.05-16.7*9.3+9.8*10.8+9.8*9.35
        =275.397+243.07-90.16-137.2525-78.085-16.7*9.3+9.8*10.8+9.8*9.35
        =275.397+243.07-90.16-137.2525-78.085-155.31+9.8*10.8+9.8*9.35
        =275.397+243.07-90.16-137.2525-78.085-155.31+105.84+9.8*9.35
        =275.397+243.07-90.16-137.2525-78.085-155.31+105.84+91.63
        =518.467-90.16-137.2525-78.085-155.31+105.84+91.63
        =428.307-137.2525-78.085-155.31+105.84+91.63
        =291.0545-78.085-155.31+105.84+91.63
        =212.9695-155.31+105.84+91.63
        =57.6595+105.84+91.63
        =163.4995+91.63
        =255.1295
    答案:22.39*12.3+10.9*22.3-9.8*9.2-17.05*8.05-9.7*8.05-16.7*9.3+9.8*10.8+9.8*9.35=255.1295
