I’m finding it surprisingly good for my workflow to use Sundays for the comic strips which mention mathematics only casually. Tomorrow or so I’ll get to the ones with substantial material, in an essay available at this link.
Scott Hilburn’s The Argyle Sweater for the 18th is a wordplay joke, based on a word containing syllables which roughly sound like “algebra”.
Jim Meddick’s Monty for the 19th is a sudoku joke, with Monty filling in things that aren’t numerals. Many of them are commonly used mathematical symbols. The ones that I don’t recognize I suspect come from physics applications, especially particle physics. These rely heavily on differential equations and group theory and are likely where Meddick got things like the 
Samson’s Dark Side of the Horse for the 22nd is the Roman Numerals joke for the week.
Thank you. And please stop in Tuesday when I hope to reach the next-to-final of my A-to-Z essays for the year.
