    i am afraid you want to write your own function other than use the built-in function in excel

    for example, suppose you want to find the hypotenuse, a, of a right triangle, which is a=square root of (b^2+c^2), u can: alt+F11, then enter

    Private Function hypo(x As Variant, y As Variant)

    hypo = (x ^ 2 + y ^ 2) ^ (0.5)

    End Function

    go back to you excel and type =hypo(3,4) in any cell, you can see the answer 5

    Actually, the functions can be defined by yourself but it is hard for me. As far as I know, there are enough functions in MS Excel for us to meet daily office work.

    In the MS Excel, you can press INSERT in the menu bar and choose FUNCTION from the pull-down menu. Then you can choose any functions from the pop-up window. The functions are also classified into many categories. I think you must be able to choose one suitable for your work.

    If you are familiar with some specific functions, you can just type it in the cell you specify,

    e.g. =IF(AND(R123<>"", R123<>0),+R123/$F$9,"").
