操作前
original c=8;shift=2;n=8;terms c/(shift+k)-c/(shift+k+1),k0..n-1
操作後
ALL interior terms cancel;S_n=c/shift-c/(shift+n)=16/5;signed remainder=4/5;reverse sum=4
條件:無
每個正的中間c/(s+k)與前一項的負值互消,留下首項與最後負項;加回帶符號餘項反核端點,不把負c的餘項改成絕對值。

操作前
same source formatting c=8;source remainder ratio text=8/10;source infinite-sum ratio text=8/2
操作後
computed partial sum REDUCED=16/5;remainder/infinite fields retain DIRECT UNREDUCED source text;numeric equivalents=[4/5, 4]
條件:無
來源只把計算出的partial sum約分,兩個直接ratio欄位可能仍為2/4或0/den;這是原輸出約定,保留字節並另核數值,不用數學等值當理由改原答案。

操作前
DECLARED whole telescoping tail;remainder at general n is(8)/(n+2)
操作後
signed remainder tends to0;full partial-sum limit=c/shift under the given index convention
條件:無
固定c與正shift給完整餘項公式,n趨無限時才推出極限;不是只因當前n的端點核查成功。
