A math meme that is funny rather than stupid:
Solve carefully!

230 - 220 × 0.5 = 

You probably won't believe it, but the answer is 5!

I am so clueless about math I don’t know what this is called… the thing where you have 3 numbers and can then figure out the fourth value.
This is how I remember doing it in school, and I can calculate it, but cannot remember what it’s called. Also, is there a way to write it out?

Another day, another math problem. Was browsing the Internet and ran across one of those math social media posts that asked to solve `8^x 2^x = 30` and decided to go all the way down the rabbit hole on the solution. Also learned a bit about spacing in math mode for LaTeX as well...
#math #nerdSnipe

Problem: Given 8^x + 2^x = 30, find x.

Start with the number of your birth month (January is 1, February is 2, and so on), add 9 squared, add 12 minus your birthday month number, multiply the value you have by itself, subtract 2.

I do not get how Python's math.modf works...
Why do I get all the zeros or nines?
4.4 | 4.0 | 0.40000000000000036
4.5 | 4.0 | 0.5
4.6 | 4.0 | 0.5999999999999996
I can fix it with... more math, but maybe I am doing something wrong?

Pedro the #Math Cat 🐈 knows that everyone has to say "big stretch!" even when it is just a medium stretch.

More importantly, stretching is a healthy activity even in medium amounts.

Nerd sniped myself this time: after getting sniped yesterday with showing that for primes `p >= 5` that `24 | p^2 - 1`, I decided to look at primes `p, q` where `p, q >= 5` and see if `24 | p^2 - q^2`.
#math #nerdsnipe

Given primes p and q where both p and q are greater-than-or-equal-to 5, prove that 24 divides p squared - q squared.

Relaxing at home and got nerd sniped again via YouTube. Looked interesting enough to give it a shot though the thumbnail was more than a bit misleading as they used `n` instead of `x` which has certain connotations associated with it.

I have a notational problem to solve. In my linear algebra script polynomials are usually capital letter named, like P,Q ∈ K[t].
Endomorphisms have capital letters from the F,G,H range.
Then in the theory of normal forms we need projection operators, which are endomorphisms, so they ought to be and are currently called P.
But then in that chapter the (characteristic, minimal, ...) polynomials move to small letters which is disturbing.
What should I do?
#math #teaching
Make polynomials small p,q ∈ K[t] throughout
Find a new name for projectors like π.
Don’t change anything, ever!

Say you have a machine that spits out hundreds of very long solution attempts to the Riemann hypothesis. Each is tedious and hard and then humans start reading it all until they refute most and finally find one that is correct. It’s a gigantic effort for the humans, but now they have a proof.
Did the machine then _solve_ the Riemann hypothesis?
