You can learn about writing in plain English in lots of places but most of it is about writing in general.
I have worked with the School of Unprofessional Writing to make a set of videos (about an hour in total) where you can learn some specifics of writing about numbers …
➡️ when to use digits instead of words
➡️ why round numbers are helpful
➡️ how to format a table to communicate rather than decorate
… and lots more.
🎨 You’ll learn that writing about numbers is art, not science.
