An arithmetically negative carry . it occurs in performing subtraction when the subtrahend is larger than the minuend in a particular digit position 一種算術負進位,它出現在某一特定的數位上減數大于被減數的減法運算中。

Look at the minuend and subtrahend . they both add or subtract the same number . the differences are the same 小結:被減數減少(或增加) ,減數也作相應的減少(或增加) ,差不變。
