Can a grumpy old ex-prof have a rant on this wet Saturday afternoon?
An enter such a =SUM(A1:A10) is a FORMULA.
A mathematical expression such as y=4x^2 + 4 is an EQUATION.
If we use the wrong terminology we will not find what we need in Help.
Happy Canadian Thanksgiving!

You could put in an equation where NA() is entered if the values entered
in A-C are blank. You could then conditionally format column D so that
NA() is formatted in the same color as the background.

I have 4 cells, A-D. Cell D is the "sum" cell. Cell D will show a "0"
on the spreadsheet if nothing is inputed into any of the 3 other
cells.

How do i write the formula in cell D so that the "0" does not show on
the spreadsheet until numbers are put into any or all of cells A-C?
