    题型：数学计算
    解:
          34.86*15.98+59.5*13.06+137.48*11.05+1491.37*4.32-(91.01*16.45+398.09*10.45+99.28*5.41+1134.28*2.12)
        =34.86*15.98+59.5*13.06+137.48*11.05+1491.37*4.32-8598.9334
        =557.0628+59.5*13.06+137.48*11.05+1491.37*4.32-8598.9334
        =557.0628+777.07+137.48*11.05+1491.37*4.32-8598.9334
        =557.0628+777.07+1519.154+1491.37*4.32-8598.9334
        =557.0628+777.07+1519.154+6442.7184-8598.9334
        =1334.1328+1519.154+6442.7184-8598.9334
        =2853.2868+6442.7184-8598.9334
        =9296.0052-8598.9334
        =697.0718
    答案:34.86*15.98+59.5*13.06+137.48*11.05+1491.37*4.32-(91.01*16.45+398.09*10.45+99.28*5.41+1134.28*2.12)=697.0718
