Hi all. Let's say that I have 10 columns and a row for each day of the
month. All odd columns contain a Dollar value and all even columns
contain a quantity. How can I multiply each Dollar amount by its
quantity and sum these for each day? An Array or sumproduct?

Example:
A1 = $2
B1 = 5
C1 = $5
D1 = 10

Answer in E1 must be 60 - (2*5 + 5*10)

Thanks.

Rob
