=SUM(A1:G1)
if you eliminate the ends you would be in trouble unless you can add empty
columns to surround the data. Sum will not have a problem with empty cells.

Is there a way to delete line items in a worksheet and still have the formula
produce a correct result? Ex: If I delete d1 then my forumal says REF!
=sum(a1+b1+d1+f1+g1)*0.7 Different lines need to be deleted at different
times and must remain in their same location if used.
Thank you
