I should have tagged this #trymathslive, like @DavidKButler does on BSky.

This little thread is because I want to add another feature to a very back-burner paper with a coauthor in functional or global analysis or something involving possibly nasty infinite-dimensional topological vector spaces.

But you have to actually know what you should prove first, and no sources I found online ever discussed this stuff in the way I wanted, let alone gave examples that test the boundaries.

My interlocutor elsewhere was taking his own approach, which is fine, but it didn't match what I was doing. I think we'll get there in the end, re: the nLab page.

Now let's return to the 60 available points for wins. My team is already taken 4 of them.
That's 56 left, the other five teams have to split those. Average is 11 per team, but you win those sets of 4. How about one team with eight points and four teams with 12 points?

Aha, then if no other team got any bonus points anywhere, my team wins!

@icecolbeveridge #TryMathsLive
Then my team could also have scored a bonus point for having at least four tries in each of the losing matches.
So best case my team that has lost four matches might have eight points on the losing matches & five points on the win for a total of 13.
(Not really sure if all this is correct, because I really don't know much about rugby)
@icecolbeveridge OK in the spirit of @DavidKButler I'm going to #TryMathsLive.
If six teams each play five games, there are 15 games played (6•5/2)
That means there are 60 regular game points available.
If my team lost four games already, but narrowly, they might have 4 bonus points. If they win the fifth game, that's four more points and maybe another bonus point for winning decisively.

It's a good morning for some #ProblemSolving !
Here's today's Q from the November Calendar.
What do you notice? What would your Ss notice?
I'm going to #TryMathLive #TryMathsLive (thanks to @davidkbutler.bsky.social for this framing)

Happy Saturday! Let's do some quick #ProblemSolving using #TryMathLive #TryMathsLive from the February Calendar of Problems.
Here is Feb 9, a great one to remind Ss of exponent laws & common base strategy.
#Algebra2 #Precalculus #MTBoS #iTeachMath #ClassroomMath #MathEd #MathsEd
Today's question: Let p be any prime greater than 3. How often will either of the integers p+1 or p-1 be divisible by 6?
#TryMathLive #TryMathsLive means I'm going to share my thinking here...
#MTBoS #iTeachMath #ClassroomMath #MathChat #MathEd #MathsEdChat #RecreationalMath #ProblemSolving

I am going to #TryMathsLive with this problem from @dhabecker.

“What is the area of the pink triangle?”

For those who like #ProblemSolving I'm going to #TryMathLive #TryMathsLive on # 21
How many integer values of n make this fraction an integer:
\( \frac{2n}{n-1} \)
Or 2n/(n – 1)

I’ll stop there. Thanks @benleis for this my first #TryMathsLive on Mathstodon!

(PS: You can explain what “inverse power reduction” means now if you like.)
