That should work for my purposes, thank you kindly

That’s very helpful if I’m feeling low energy and don’t want to deal with pi. Thank you.

I’m teaching a little group theory to my number theory class to more deftly explore the units in a mod. I want to design a project about groups in the wild, and thought puzzles/games might be good, I.e. the moves you can make on a Rubik’s cube form a group. That spark any ideas for anyone?

If you’re in a bind and really need to approximate the number 31, try cubing π

Yes agree - it seemed like a standardized text or some sort

From the askmath community on Reddit: i got 76, book says 28 Explore this post and more from the askmath community

My god, an entire Reddit thread about the terrible PEMDAS math meme! But an actual real life book that has both ambiguous answers as multiple choice options AND has the correct answer as not the one I’d choose haha

Good work

(We have not done the Chinese Remainder Theorem yet, purposely wanted to see what they would do without it)

Simple problem we worked on today in Number Theory:

X=3 mod 5
X=5 mod 7
X=7 mod 11

We figured out a solution with some grit but there were some interesting clever ideas that the students had that I enjoyed.

I’m not sure I would know how to do this TOTALLY by hand but I used the approximate zeros to help me locate the exact zeros, then divided those out to find the non-real ones

I’m just glad BlueSky is feeling a little bit like old twitter…

I agree - that’s what we started with and it was fun!

Yes! I do for sure. Dm me your email

Yeah whoops haha damn autocorrect

‘Nickname’ is not ‘nick’ + ‘name.’

It was originally ‘ekename.’

‘Eke’ was the Middle English word for “also” or “in addition.”

Since ‘ekename’ began with a vowel, people used ‘an’ before it.

Over time, 'an ekename' became 'a nickname.'

hahahahahah i didn't even notice that!

Ok this was my instinct so YES! And thanks for the extensions.

Starting Number Theory elective tomorrow. Either going to start w the Chicken Nugget problem (if nuggets come in packs of 5 and 8, what’s the max amount that you cannot buy?) or having them try to explain the disability rules (why does adding the digits to a multiple of 3 work?). What would you do?

RIGHT IN MY VEINS

Consider myself warned

Since when do you give joke warnings?!?!

Snow day today — probably snow day tomorrow? Jimmy Carter funeral on Thursday means we can’t be at school. Professional day on Friday. This is a hilarious re entry after break for us in DC!

Save this for a few months…

(20²5) + (2⁰25)

They need better parentheses… Tiny (desk concert)

Phew!

Going to do a collab with the 4th graders with my senior data science class in January. What should we do??? So excited but need to think of a fun 20-30 minute activity

Is there going to be a new power color in the next wingspan expansion!??? (Def not going to answer that but I tried!)

Update: this is by far the most engagement I have gotten on a BlueSky post, have confirmed that BlueSky is indeed, Philly forward

Good point. I will make a starter pack with just you in it
