I’m only going to say this once but if I’m doing a sum and you want me to do it in a specific order, use brackets. That’s what brackets are for. Don’t expect me to do things in a predetermined order because I literally can’t be bothered and I will never care enough to do that. I’m already doing a sum so don’t push it, okay bud

Very funny joke, but I don't agree with the division sign. Its supposed to be either a / or \ depending on which way you want to divide.

Jokes and tricks that hinge on unclear communication (eg: not using parenthesis or other notation to make intent clear), and then are smug when people are tricked, remind me of the old xkcd https://xkcd.com/169/

I just saw some jokes about factorials so at least I got this one, heh.

Sorry but what is unclear in OPs image?

Can someone explain to me why this is funny?

[–] [email protected] 0 points 2 weeks ago (1 children)

So with people who do order of operations incorrectly, you have 25-5 =20 and then divide it by 5 and you get 4.

However the correct answer is 24 since you do the division first.

Where the joke comes in is he states “4!”, which sounds like he is emphatic about the wrong answer. However an exclamation mark is “factorial” which translates to 4x3x2x1… which happens to equal the correct answer of 24.

Ah! :D I like it.

Thank God this meme is muted

[–] [email protected] 0 points 2 weeks ago (7 children)

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.

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.

4! Is a factorial which means it's 4 x 3 x 2 x 1 = 24

[–] [email protected] 0 points 2 weeks ago

Totally missed that. Thank you.

[–] [email protected] 0 points 2 weeks ago

The exclamation point denotes the factorial function. 4! = 4 ⋅ 3 ⋅ 2 ⋅ 1

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

Cause math people has a weird humor?

The exclamation point in the answer, from a math perspective, makes it 4 factorial: 4 x 3 x 2 x 1 = 24, which is the correct answer.

Could it be you’re responding to the wrong person?

[–] [email protected] 0 points 2 weeks ago

Indeed, it could.

4 factorial

[–] [email protected] 0 points 2 weeks ago* (last edited 2 weeks ago) (17 children)

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

[–] [email protected] 0 points 2 weeks ago (4 children)

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

for those that didn't get it: clever factorial = brilliant

[–] [email protected] 0 points 2 weeks ago

Ok this is funny

Best math meme so far.
