〖1/1算式〗
    作业：求算式 ((96-94.5)^2+(100-94.5)^2+(87-94.5)^2+(94-94.5)^2+(98-94.5)^2+(92-94.5)^2)/6-1 的值.
    题型：数学计算
    解:
          ((96-94.5)^2+(100-94.5)^2+(87-94.5)^2+(94-94.5)^2+(98-94.5)^2+(92-94.5)^2)/6-1
        =(1.5^2+(100-94.5)^2+(87-94.5)^2+(94-94.5)^2+(98-94.5)^2+(92-94.5)^2)/6-1
        =(1.5^2+5.5^2+(87-94.5)^2+(94-94.5)^2+(98-94.5)^2+(92-94.5)^2)/6-1
        =(1.5^2+5.5^2+(-7.5)^2+(94-94.5)^2+(98-94.5)^2+(92-94.5)^2)/6-1
        =(1.5^2+5.5^2+(-7.5)^2+(-0.5)^2+(98-94.5)^2+(92-94.5)^2)/6-1
        =(1.5^2+5.5^2+(-7.5)^2+(-0.5)^2+3.5^2+(92-94.5)^2)/6-1
        =(1.5^2+5.5^2+(-7.5)^2+(-0.5)^2+3.5^2+(-2.5)^2)/6-1
        =107.5/6-1
        =17.916667-1
        =16.916667
    答案:((96-94.5)^2+(100-94.5)^2+(87-94.5)^2+(94-94.5)^2+(98-94.5)^2+(92-94.5)^2)/6-1=16.916667
