please pick a number between 1 and 22. Explain your answer.
6. It's a pretty good prime number and I haven't used it in an ask yet.

The phrase "give a single fuck" implies fucks form part of a group with a multiplicative identity. However, they are not commutative because giving a fuck before an event has a different effect than giving a fuck afterwards. This also implies that there is a multiplicative inverse to giving a fuck, which in general can be shown to be true.
Thus, fucks can form a non-commutative multiplicative group.

My triangle subdivisions
prime numbers higher than four are hard.  Hence why I skipped 11.

I had some fun asking ChatGPT about cases from "Counterexamples in Analysis." You get this kind of uncanny valley math, syntactically and stylistically correct but still wildly wrong.
This was a response to "Prove or disprove: there exists a nowhere continuous function whose absolute value is everywhere continuous." It responded in TeX, which I coped into a TeX editor.

rb this with your favorite math concepts/books/videos... things u enjoy and that make you excited! (or reply but i want to hear about it and if you rb it then i hear more cool stuff from more people)
my favorite books are the grapes of math and things to make and do in the fourth dimension. i'm also reallyyyy wanting to read number freak and godel, escher, bach. concepts i love are chaos theory, non-euclidean geometry, and dimensions beyond 3rd!

For a limited time only, I am offering THREE (10) free mathamancy consultation(s) to anyone who can help me banish these Ternary Terns before they cover my entire tower in triangular bird shit.

Could u answer this question, my Brainly isn't working and I already asked a bunch of blogs this question:
A club consisting of 11 men and 12 women needs to choose a committee from among its members so that the number of women on the committee is one more than the number of men on the committee. The committee could have as few as 1 member or as many as 23 members. Let N be the number of such committees that can be formed. Find the sum of the prime numbers that divide N.
PLEASE ANSWER ASAP!! THANK YOU!!!
plz read my description next time 🫡 my dumbass does not specialize in math. ik how to solve this one so i'll do just this once ;)
Tumblr media
So, in conclusion, the sum is 81.
Might want to double check if u know how to solve later, because I don't even trust myself 🤡💕

Despite 65536 literally being 2¹⁶, it still feels like a weirdly "odd" number. It's like the opposite of 5, which is an odd number that feels weirdly even.

Sierpinski-triangle and Pascal"s triangle
Tumblr media
Pascal"s triangle
I used transparent/translucent paper to color the numbers of pascal"s triangle.
Each color represents a prime number:
Red: 2
Orange: 3
Yellow: 5
Green: 7
Blue: 11
Violet: 13
For each layer (and the according prime number) I colored the numbers of pascal"s triangle if the pascals triangle number is divisable by that prime number.

The advantage of this transparent/translucent paper I used:
You can hold multiple layers against the light (and see the overlapping colors):
2 and 3:
Tumblr media
^For instance: if you look at the 6 in the 5th row it is a combination of red and orange - 2 and 3 - as 6 is built up by the primes 2 and 3 (2*3)
2 and 3 and 5:
Tumblr media
3 and 5 and 7:

[Afternote: I just realized I forgot to color some numbers in the modulo 2 sheet (red). ]

idk but 1.5 × 6 = 9 feels soooooo strange to me. it should be wrong. it should equal something else like 7.5
