The SUM(H24:H25) if that is what you meant is a function
and sums the cells in the range.

The rest of the parens (parentheses) can be used to change
the order of operations. Since multiplication and division take
place before additions and subtractions they don't really matter here.

The formulas are like what you use in algebra.
See your Excel Help for "order of operation" or specifically
"about calculation operators".

Also look at "functions" in your Excel help.

I have a formula: =(h24*j24)+(h25*j25)/sum(h24:25)

But I have no idea how many parentheses I am suppose to place around the
formula or what additional ones I need other than the one that surround the
indivudual formula.
