The way I see it is that multiplication is another form of additon (which is
an extended form of counting)...

to get 3x5 you can add 5 three times...

Same applies to DCOUNT/DSUM and SUMPRODUCT... with the former you can only
count/sum... with the latter you can cound/sum AND multiply...

I'm reviewing a workbook that has DCOUNT all through it in places where I'd
probably use SUMPRODUCT. Is there some guidance where to use one over the
other. Was DCOUNT available before SUMPRODUCT?
