@KarenCampe That's a fun journey ... some people are in it for the fun, some take it more seriously.

I like a puzzle that can be met on many levels.

@ColinTheMathmo @KarenCampe It’s gotten my kids hooked now too ;-)

Thus, for EVERY prime p > 3, either p-1 or p+1 must be divisible by 6.
How often? ALL THE TIME.

That was fun! Please share how you thought about it.
And check out the January Calendar of problems for more

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...

I've added one more thing to my newest blog post "Shout Out for Squares!"

It's the "dividing a square into rectangles" discussion that happened here a few months back, with @johncarlosbaez and @Mathforlove highlighted. THANKS!!

@KarenCampe @Mathforlove - I'm glad you're standing up for inclusive definitions. They're more powerful.

KarenCampe,

@johncarlosbaez @Mathforlove
Always!! I'm team inclusive.
To be fair, they are more useful once students have had some experiences with the different categories. I consider the inclusive def to be an "upgraded" definition that shows more connections.

Happy SEVENS day (7-14! Or 14-7 for those who use DDMM) and here's my 2021 post celebrating Super Sevens!

(Recent updates include heptagon images from the amazing Hannah Murray @MurrayH83 using 21st century pattern blocks)

@KarenCampe This year is also divisible by 7. You can see that in one of two ways (among others).

2023+70 = 2093, then you can add another 7 to get 2100, which is clearly a multiple of 7.

Or we know 1001 is a multiple of 7, so compute 2023-2002 giving 21, which is a multiple of 7.

So 7 divides into 2023 leaving 0 remainder.

Which is nice.

@ColinTheMathmo Indeed it is!! Wow, I hadn't noticed that earlier. I will edit the post!

A wonderful explanation from Grant Sanderson 3Bue1Brown about the divided circle problem & the reasoning WHY there are 31 regions with 6 points (not 32 as pattern might suggest).

https://youtu.be/YtkIWDE36qU

I'm really excited because I've never seen this explained before & the connections are wonderful! (I've only ever seen it as an example of not assuming patterns continue with only inductive reasoning evidence... I think HS math Ss can grasp this by algebra 2...)

@KarenCampe
What a brilliant video! I will need to sit down and devote some serious thinking time to play with the ideas.

ColinTheMathmo,

@dhabecker @KarenCampe I use this example in some of my talks, and always take time to explain why it's happening, not just leave it as another "crazy thing that happens in math and you'll never understand".

There's a reason, we can work it out, and it's deeply satisfying to do so.
