These may not cover every base, but they probably cover at least one base that you don't see covered much ;) Today's going to be a"fun with awk" day. I figure we should have one now because we never had them in school when I was a kid... The topic, as the title suggests, has to do with columnar arithmetic or, less pompously put, performing arithmetic operations on columns or, even more accessibly, adding stuff up ;) It's somewhat like our older post on doing simple cumulative math with awk, but slightly more confusing.
