Range A1= 15,10,1,8,1,9,0,1
Range A2= 15,10,1,8,1,9,0,1

I need 8 different formulas for A3-A10 to get the sum of each position.
So A3 would only get the sum of the first number in A1 and A2 (30)
A4 would get the sum of the second number in A1 and A2 (20)
A5=2
A6=16
A7=2
and so on...

Is that do-able?

Thanks,
Kevin
