User blog comment:Swooped me in one hit/my first attempt at creating notation./@comment-29310326-20170215142453/@comment-30754445-20170215163642

Pros: It's straightforward, and it gives decent numbers (for a first try)

Con: the second step has little power when compared to the first. There's no need to write 5-6-10 when we could simply write 5-60.
