|1/101-1/99|-|1/100-1/99|-|1/100-1/101|,|1/101-1/99|-|1/100-1/99|-|1/100-1/101|,|1/101-1/99|-|1/100-

|1/101-1/99|-|1/100-1/99|-|1/100-1/101|,
|1/101-1/99|-|1/100-1/99|-|1/100-1/101|,

|1/101-1/99|-|1/100-1/99|-|1/100-1/101|,
先去除绝对值,将上式化成
1/99-1/101-(1/99-1/100)-(1/100-1/101)=1/99-1/101-1/99+1/100-1/100+1/101=0

!第一第二个家负号!去绝对直!地三直接去你就会了
