Multiplying columsn and addin the results
In a spreadsheet I have numbers in the first row of each column from A to ?
The numbers has to be multiplied like this A1*B1, C1*D1, E1*F1 and so on. Finally the results have to be added.
Is possible in a single formula without entering all the single multiplications in a SUM(); something like =Sum(A1*B1:AX1*AY1)?
