Welcome
Hi Fredg999,
Great news to have a math teacher on board. Especially the accessible for beginners part raises my hopes that I will understand one or the other in the near future. --Xenwolf (talk) 21:22, 3 July 2021 (UTC)
Thanks
... for removing the section anchor here. Sometimes it's too easy to forget your last clicks before copying an external link. There is a really helpful plugin for Firefox and Chrome that copies builds you a link combined of URL and title in several markup languages including MediaWiki (see the Copy URL To Clipboard home page for more). By using it, I sometimes forget to check the URL part. So again thanks for fixing this.
On the other hand, I have to say that I don't like a change you did to the introduction of octave reduction at all, please see related discussion topic. --Xenwolf (talk)
