大家好,感謝您的幫助。C#語言,計算器
我用C#製作了這個計算器,並且遇到了一個問題。 當我添加類似5 + 5 + 5它給了我正確的結果,但是當我想減去兩個以上的數字,也劃分或乘以兩個以上的數字,我沒有得到正確的結果。
你知道我做錯了嗎,
非常感謝!

地方一個破發點,並通過代碼逐行步驟,看看結果是在每個點期望,一旦你看到它出錯的時候,你就會知道如何解決它 – RhysW
提示:科學計算器使用括號來分割每個數字以顯示優先級是有原因的,例如,你的數字是10,你想除以10,然後除以2,10/10 = 1,1/2 = 0.5但這不同於10除以(10/2),其中10/5是2而不是一半,BIDMAS對於理解 – RhysW
