    题型：数学计算
    解:
          0.7+0.97+0.997+0.9997+0.99997+0.999997
        =1.67+0.997+0.9997+0.99997+0.999997
        =2.667+0.9997+0.99997+0.999997
        =3.6667+0.99997+0.999997
        =4.66667+0.999997
        =5.666667
    答案:0.7+0.97+0.997+0.9997+0.99997+0.999997=5.666667

    解:
          2+3+5+8+13+21+34+55+89+144+233+377
        =5+5+8+13+21+34+55+89+144+233+377
        =10+8+13+21+34+55+89+144+233+377
        =18+13+21+34+55+89+144+233+377
        =31+21+34+55+89+144+233+377
        =52+34+55+89+144+233+377
        =86+55+89+144+233+377
        =141+89+144+233+377
        =230+144+233+377
        =374+233+377
        =607+377
        =984
