Help with wc and subtraction needed

["Matthew Benjamin" <msbenjamin12@xxxxxxxxx>]

I have a command that I am trying to read a particular amount of lines with

wc -l somefile | awk '{print $1}' 

when it givs the number of lines, I am trying to find out how to use that number in an addition problem. Can someone help me with that?
