    题型：数学计算
    解:
          (2.5-0.1)*5+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*(3.4-0.1)
        =2.4*5+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*(3.4-0.1)
        =2.4*5+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*3.3
        =12+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*3.3
        =12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*3.3
        =12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+5.6*2+5*2*2*3.3
        =12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+5*2*2*3.3
        =12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+10*2*3.3
        =12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+20*3.3
        =12+21+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+66
        =33+8.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+66
        =41.1+1.9+2.7+1.7+17+8.4+5+2.7+6.3+11.2+66
        =43+2.7+1.7+17+8.4+5+2.7+6.3+11.2+66
        =45.7+1.7+17+8.4+5+2.7+6.3+11.2+66
        =47.4+17+8.4+5+2.7+6.3+11.2+66
        =64.4+8.4+5+2.7+6.3+11.2+66
        =72.8+5+2.7+6.3+11.2+66
        =77.8+2.7+6.3+11.2+66
        =80.5+6.3+11.2+66
        =86.8+11.2+66
        =98+66
        =164
    答案:(2.5-0.1)*5+3*7+8.1+1.9+2.7+1.7+17+8.4+5+2.7+2.1*3+5.6*2+5*2*2*(3.4-0.1)=164
