Hey guys, new to this forum but not forums in general. Your help is appreciated!

I want to sum each row in a single column, example:

=J12+Q12
=J13+Q13
=J14+Q14
...ect
Can I enter one formula in a new column to add each separate row together, or do I "HAVE" to enter the formula for each row like I have been doing?

I have many sheets to do this to and would like to speed it along! Thanks for listening!
