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...
Everybody forgets the factorial...
Or if you don’t know order of operations, then you probably also don’t know factorials, so 20 / 5 = 4
4! Is a factorial which means it's 4 x 3 x 2 x 1 = 24
Totally missed that. Thank you.
4 factorial
The exclamation point denotes the factorial function. 4! = 4 ⋅ 3 ⋅ 2 ⋅ 1
I see no one has explained yet, so I'll give it a shot. He is excited about math, and that needs to be encouraged.
The exclamation point makes it right. The formula, when worked with proper order of operations, equals 24, which is equal to 4 factorial (4!) 1 * 2 * 3 * 4=24
Best math meme so far.
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.
You might find Lojban interesting if you are not already aware. (I haven't tried to learn it myself, I just know it exists)
Relevant xkcd
I believe you mean, "nice pun!"
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!
Comment section full of people looking for an opportunity to argue
No it isn't
Yes it is
Wait, will this be the 5-minute or the half hour?
Ok this is funny
You got the wrong symbol in the headline, it should be >3
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.
Clever! lol
for those that didn't get it: clever factorial = brilliant
Thank God this meme is muted
