This one is courtesy of frequent commenter, wst. It’s really a PoSWW, but the ideas may be sufficiently unfamiliar for it to be worth encouraging WitCHlike discussion. It comes from the Cambridge textbook General Mathematics 1&2.

PoSWW 26: Elevated Concern
Yeah, it’s been a while. We’ve been busy. But, hopefully we’re now back with normal transmission, and we’ll start with an easy one, courtesy of Mysterious Michael. It is an exercise and solution from Cambridge Essentials Year 10/10A.
WitCH 79: Cos Why Not?
Yeah, we’re busy, but this one has been bugging us. It is an exercise and solution from Cambridge Specialist Mathematics 3&4. It’s basically a PoSWW, or we could simply let it pass as a textbook glitch. But we think there’s more than the obvious to say.
Yet More Mathematics Books, Free to More Homes
Same as last time, and last last time. This pile is mostly graduate texts, with quite a few classics, but there are also some excellent undergraduate texts, and some oddballs.
Please comment below or email me if you have any interest in any of the books or if you have any questions. Quickly. I’m happy to consider meeting up here or there in Melbourne, but I definitely won’t be mailing any books this time. I’m tired of people not saying thanks.

Governor DeSantis’s Critical Race Theory and the Rejection of Mathematics Texts
Last week, the big, crazy news out of big, crazy America was the Florida Department of Education’s decision to reject 54 school mathematics texts. The reasons? Well, supposedly the rejected texts
included references to Critical Race Theory (CRT), inclusions of Common Core, and the unsolicited addition of Social Emotional Learning (SEL) in mathematics.
The claim was immediately undermined, however, by the FDOE’s declining to provide any such references, or to even identify the rejected texts. Continue reading “Governor DeSantis’s Critical Race Theory and the Rejection of Mathematics Texts”
More Mathematics Books, Free to More Homes
UPDATE (25/11/21)
OK, all done. Thanks to those who expressed interest, and thanks in particular to MyCool, for playing the role of sweeper. Books will be handballed as arranged.
********************************************************
Or the same homes. I couldn’t care less.
This pile of books is not nearly as extensive or as high quality as the last bunch, and I’m not going to work hard to find homes, or to deliver the books to the homes. Still there are some good books there for undergraduate maths and engineering folk, and a few classics. Continue reading “More Mathematics Books, Free to More Homes”
PoSWW 20: Unconventional Wisdom
This one comes courtesy of frequent commenter, John Friend. It is an example from Cambridge’s Mathematical Methods 34.
UPDATE (19/08/21)
It amazes me at times what does and does not concern some commenters. That’s not intended as a criticism. Well, it is, but it isn’t. And, it is. It’s complicated.
WitCH 63: A Separate Reality
The following comes courtesy of frequent commenter, John Friend. It is an exercise and solution from Cambridge Specialist Mathematics 3&4.
PoSWW 17: Blessed are the Cheesemakers
This one is old, which is not in keeping with the spirit of our PoSWWs and WitCHes. And, we’ve already written on it and talked about it. But, as the GOAT PoSWW, it really deserves its own post. It is an exercise from the textbook Heinemann Maths Zone 9 (2011), which does not appear to still exist. (And yes, the accompanying photo appeared alongside the question in the text book.)
WitCH 59: Stretching the Truth
This double-barrelled WitCH comes from Maths Quest Mathematical Methods 11 (top). and Cambridge Mathematical Methods 1 & 2 (bottom). It is the final in our series of Quest-bashing, at least for now.
