On Sunday I published a video and a blog post on the @aperiodical about a really nice puzzle/solitaire game invented by Ed Kirkby, which I call "Double Back".
Have a look: https://aperiodical.com/2023/12/the-double-back-puzzle-is-a-nice-mix-of-towers-of-hanoi-and-solitaire/

Interesting commentary on online grading portals, parenting, & relative focus on grades vs. learning.

Not that difficult, but a nice question: Calculate the area of the blue region.

I buy most books second-hand from wob.com these days. It's based in the UK, so they rarely have foreign books I'm looking for.
Are there any similar shops either in the UK or that can deliver to the UK, that stock books from elsewhere?

I don't know why people expect Large Language Models to be good at math.
It's like when our students just memorize tons of problems without any deep conceptual understanding and spit back whatever they think of first...

A garbled version of my essay appears at https://show-hn.com/2023/10/22/apt-arithmetics-of-distance/ . It looks like it was translated into another language before being translated back into English. Anyone know who would create such a thing and why? (And am I risking anything by Approving it via WordPress?)

The things a square root acts upon are held together by a vinculum. I wonder what it would be like if that was how we did it for all functions?

Mathematicians and math educators only, please. Which is correct?
(Background - Math was my best subject, but it was decades ago, and now that I’m tutoring my niece I run into things like this… This is a genuine request for assistance, not a trap!)

At some point, probably long after I left a math class, I started assuming the square root sign meant both roots. I am now becoming aware that it only means the principal (positive) root, and if you want both roots you have to be explicit.

Comments very welcome.

I've been thinking lately about how nonverbal I am when I'm moving about.
If I have an interaction with someone, like they let me past or I let them past or something notable happens, I can manage a smile or a noise like "huh!" but it takes me a good few seconds to work up the ability to speak, usually too long for it be worthwhile.
I think my brain is busy processing what's happening, and trying to come up with an appropriate response. I usually work out what I should have said about a minute down the road.
I suppose the worst case is that I come off as grumpy or stupid, but it'd be nice to be able to have a bit of chat with people.

A question for teachers, but I'd welcome thoughts from others.

In teaching, should one talk about a quadratic equation such as x^2+10x+25=0 as having one solution or a repeated solution, and do you think it matters?

If you're at all interested, or think some of your followers might be, then I'd be delighted if you would boost this for reach ... thank you.

The fateful day has arrived: I've got a new debit card, so I have to work through everything online that has my card details and update them.

Might end up like Chas & Dave after saying "debit" so much.

Taught my daughter C how to factorise quadratics today by focusing on the sum coming out to the coefficient of x before the product coming out to the constant term. It worked extremely well.
