计算(-1+1/100)x(-1+1/101)x(-1+1/102)x...x(-1+1/2013)=
计算(-1+1/100)x(-1+1/101)x(-1+1/102)x...x(-1+1/2013)=
计算(-1+1/100)x(-1+1/101)x(-1+1/102)x...x(-1+1/2013)=
(-1+1/100)x(-1+1/101)x(-1+1/102)x...x(-1+1/2013)
=(-99/100)x(-100/101)x(-101/102)x...x(-2012/2013)---(前一项的分母可以和后一项的分子约分)
=-99/2013
希望能够帮助你,有疑问欢迎追问,
-99/100*(-100/101)*....*(-2011/2012)*(-2012/2013)=-99/2013
