6-5/28-7/28-9/28-.-23/28=计算

6-5/28-7/28-9/28-.-23/28=计算
=6-(5/28+23/28)+(7/28+21/28)-……-(13/28+15/28)
=6-1-1-……-1
=6-1×5
=1

6-5/28-7/28-9/28-................-23/28
=6-(5+23)/28-(7+21)/28-(9+19)/28-(11+17)/28-(13+15)/28
=6-1-1-1-1-1
=1

6-5/28-7/28-9/28-................-23/28
= 6-（5+7+9+….+23）/28
=6-5*(5+23)/28
=1
