I need to multiply two cells with numbers, then add that to two cells with
numbers that multiply each other, then add that to two cells that multiply
each other.

In simpler times, in the past with Excel 2003, I believe I achieved that by
using the following. Can you correct me for Excel 2007?

=SUM(A1*A10)+(B1*B10)+(C1*C10)

Thank you...

You don't really need the SUM function. This should accomplish what you want:

=(A1*A10)+(B1*B10)+(C1*C10)

Even the parenthesis are technically redundant and could be removed, but I
would include them anyway just because it's easier to read.

Try it like this:

=SUMPRODUCT(A1:C1,A10:C10)
