計算機常用函數公式主要有：SUM函數、ABS函數、AND函數、AVERAGE函數、IF函數、COUNTIF函數、RANK函數等。
電子計算機（electronic computer）通稱電腦，是現代一種用於高速計算的電子計算機器，可以進行數值計算、邏輯計算，具有存儲記憶功能，能夠按照程序運行，自動、高速處理海量數據。
它由硬體系統和軟體系統所組成，沒有安裝任何軟體的電腦稱為裸機。電腦被用作各種工業和消費設備的控制系統，包括簡單的特定用途設備、工業設備及通用設備等。
計算機內部電路組成，可以高速準確地完成各種算術運算。現今電腦系統的運算速度已達到每秒兆次，微電腦也可達每秒億次以上，使大量複雜的科學計算問題得以解決。
計算機不僅能進行精確計算，還具有邏輯運算功能，能對資訊進行比較與判斷。計算機能把參加運算的資料、程式以及中間結果和最後結果保存起來，並能根據判斷的結果自動執行下一條指令以供使用者隨時調用。
電腦內部的記憶體具有記憶特性，可以儲存大量的資訊。這些信息，不僅包括各類數據信息，還包括加工這些數據的程序。
這個就是電腦上鍵盤所有鍵的功能。
