|1/1001-1/1000|+|1/1002-1/1001|-|1/1002-1/1000|=?|1/1001-1/1000|+|1/1002-1/1001|-|1/1002-1/1000|=?|1

|1/1001-1/1000|+|1/1002-1/1001|-|1/1002-1/1000|=?
|1/1001-1/1000|+|1/1002-1/1001|-|1/1002-1/1000|=?

|1/1001-1/1000|+|1/1002-1/1001|-|1/1002-1/1000|=?
因为1001>1000
所以1/1001

分子相等时,分母越大,值越小。
所以,原式=1/1000-1/1001+1/1001-1/1002-1/1000+1/1002
=0

0

原式=1/1000-1/1001+1/1001-1/1002-1/1002+1/1000 =2/1000-2/1002=1/500-1/501=1/(500X501)=1/25500

贝多芬说,一切数学题答案都是0,填0准没错,经证实,确实如此.哎,多快的速度哟
