This is quite possibly the best maths joke I've ever seen.

[edit] I guess it still can't beat the 'be rational' / 'get real' one.

007 will never get this wrong, it's 4, 24.

I understand why this is wrong (order of operations dictates the division happens first, so it's really 25 - 1 = 24), but why is it funny? I don't mean "This isn't funny," I think I'm just missing the joke.

4! Is meant to be 4 factorial. 4! = 4 x 3 x 2 x 1 = 24

Aha! Got it, thank you so much.

And here I was thinking I was still decent at math. I got bamboozled...

You got the wrong symbol in the headline, it should be >3

Comment section full of people looking for an opportunity to argue

[–] [email protected] 48 points 2 days ago (1 children)

No it isn't

[–] [email protected] 20 points 2 days ago (2 children)

Yes it is

Wait, will this be the 5-minute or the half hour?

"I'm sorry, I cannot continue to argue, unless you pay."

[–] [email protected] 4 points 1 day ago

You're not arguing, you're just being contrary!

[–] [email protected] 4 points 1 day ago

Hah, joke's on you, I just need 4!

Best math meme so far.

[–] [email protected] 50 points 2 days ago (1 children)

4! = ...Wait, that's literally the point of the post this time

It's about time there was a real argument in here

ASCII hack failure of language. Even in mathematics, ! has multiple meanings like with Boolean NOT. We need a science, math, and language reformation to remove non intuitive narcissistic names, and implied contextual meanings.

[–] [email protected] 7 points 2 days ago (1 children)

I've never seen ! used for boolean NOT in maths, just ¬. I think ! is something programming languages went for because it's easier to type. That said, screw (a, b). Is that a (coordinate) pair, an interval, an inner product, some secret fourth thing? Who knows!

You might find Lojban interesting if you are not already aware. (I haven't tried to learn it myself, I just know it exists)
