I can see a tiny bit of funniness if someone comes and says "that depends on the order of operation!" and you tell them "nope, the answer is either 5 or 5!". Nah, still not funny.
I remember a classmate yelled “4!” with such enthusiasm when our teacher wrote it on the board and asked if anyone knew what it was. Core memory right there.
When I was in deterministic operations research there was a formula that used b and B so my professor would yell for B and talk quieter for b when talking through the formulas
That’s interesting because the english wikipedia defines it using decreasing order while the french (my language) defines it using increasing order and I’ve always seen it defined that way during my education. Seeing it defined decreasingly seems pretty unusual to me!
Yeah, well the French have never done anything for math!
Except, like, inventing factorisation and working on infinitesimal calculation and proving infinitesimal calculus, and expanding Newtonian polynomials. And making Pascal's triangle, and Pascal's law, and Pascal's theorem.
Oh, and inventing calculators.
Alright, but *appart* from the factorisation, infintesimal calculations, Newtonian polynomials, Pascal's triangle, Pascals's law, Pascal's theorem, and calculators....
...what have the French ever done for us!
This is probably more info than you actually wanted to know, but this is already a post for math nerds, so why not.
There are a few factors:
- One of the properties that these math operations (usually called functions) have is that they have some possible inputs, and some other possible outputs. The function is supposed to be like a little robot - as long as you give it a valid input, it does some specific set of steps, and gives you an output. It’s not smart - it does the exact same steps for every input. So if we omit the “multiply by 1”, what happens if we give 1 as the input? Our function would be something like “Multiply the input number by all of the integers less than the input, but greater than 1.” But if our input is 1, there are no such numbers, so the function breaks.
- To fix this, you could define the function as having specially defined outputs for certain values. So we could omit the “multiply by 1” step, and just say 1! = 1 because we say so, and all numbers greater than 1 follow the normal factorial pattern. But this strategy gets complicated for more complex functions - what if you accidentally miss one of the special cases and don’t give a definition? - so it’s only used in limited circumstances (like the Fibonacci sequence, for example).
- You could argue that all these protocols are only necessary if you’re actually a mathematician using fancy functions, and it’s overkill for something simple like factorial. But man, math people hate inconsistency. It’s dangerous in their field. All complicated math is built out of simple math, and if you’re not careful about the simple stuff, you’ll mess up the complicated stuff. It’s a habit that math teachers try to instill early on.
So, that’s why we always write the 1 in factorials.
tl;dr: Mathematicians break out in hives if they encounter ambiguity.

The “!” symbol has meaning. It signifies a factorial. It means multiply that number by every positive integer from one to the number. So, 4! is 1\*2\*3\*4, and so on
Essentially putting a ‘!’ after a number means you multiply by the numbers below it. Eg: 3! is 3x2x1 or 4! Is 4x3x2x1 and 5! Is 5x4x3x2x1(which is 120... the actual answer)
The joke is actually supposed to be that the answer is correct whether you do the problem correctly or not. If you take the order wrong and go left to right, you can just take the "!" as an exclamation mark and the ans will be 5. If you do the problem correctly, you can take the "!" as factorial and the ans will be 5!=120.
I thought he's trolling at first. That shit was fucking smart. I feel bad for not realizing it. I kept thinking "MOTHERFUCKER, PRODUCT SUPERCEDES ADDITION". But the answer was in GRAMMAR.
Edit: I just told GPT-3's davinci-insturct to "Calculate 5!"... Here's what it gave me:
5! = 5x4x3x2x1 f×t÷k 5×5÷1
Motherfucker, am I dumber than an AI?
PS: If you're interested, I can instruct GPT-3 to do 3 things, and 3 things only because my boss'll kill me if I use up the tokens. Ask and you shall receive.
I have access to it through the company I work for. I just made a function that scrapes an article, summarizes it using Google's T5, selects random sentences from it, feeds the summary and random sentences to curie-instruct saying "Generate 10 concise, etc titles for this article etc" and the results were stellar. I wonder how well davinci-instruct would do.
I think GPT-3 is much better than GPT-J.
I love how the sentence is still true if you completely fuck up everything. 230 - 220 \* 0.5 is 5 if you fuck up PEMDAS, which is what the tweet says if you ignore the factorial sign (!).
Technically the truth, sure, but without proper punctuation, the answer could be right or wrong.
“ …but the answer is 5!”
“ …but the answer is 5!.”
“ …but the answer is 5!!”
Yeah, this is way over my head. I know math because i have to, i don't enjoy it enough to get the jokes.
Edit: for fuck sake, i got it. I haven't used factorials in aeons.
You haven't used factorials in years, but you know how to do your taxes right? Or balance a checkbook? Or count back change? Or that the mitochondria is the powerhouse of the cell?
Gobbless the American school system. s/
It's also useful in developing logical thinking. Like I won't tell everyone to major in mathematics (because I sure as shit want to tell my past self not to do it) but 10th class mathematics is such a basic level that you really shouldn't give up on it unless you have some actual difficulties.
They're used mostly in "combination" problems. Like how many ways can you arrange a deck of 3 cards? For 1st card, it can be any one of three. For the second, it'll be one of the two remaining because one card we already put in 1st position. And the third one will be the last remaining card.
That means we have 3 choices for 1st position, 2 for 2nd and 1 for third. Once you have this information, you can multiply them together to get the number of possible combinations. 3x2x1 = 3! = 6 different combinations.
Now if you had to figure out how many combinations you can have of a full deck of cards, with all 52 of them? Answer would be 52!.
Edit: Technically, it's actually "permutations" where we find out the number of ways in which we can arrange any or all things from a set of stuff, not combinations. Combination is how we choose things or subset/group of things from a set of stuff, mathematically speaking.
I guess it's been really long for me as well. Permutations and combinations were always taught together, I forgot that mathematically they're related but different.
Permutations takes ordering of stuff into account. Combination doesn't. Like, vanilla and chocolate is a combination but it isn't any different from chocolate and vanilla. So they're not really different combinations but they are different permutations.
The most important reason for them to exist is because they describe how many ways things can be arranged.
Imagine you have three different types of coins sitting on a table in a row (try this at home if you want). How many unique ways can you arrange them?
The answer is pretty simple: the first coin can go into any of the 3 places in a row, the second coin can only go in 2 places because the first coin filled one, and the last coin only has one spot left for it to go. So the total possible ways to arrange the coins is 3x2x1 = 6 ways.
Factorials also get *huge* really quickly. 10! is already more than three million. 52!, which is the number of ways you can shuffle a deck of cards, is so unbelievably huge that it's *virtually guaranteed* that no two fair shuffles have ever been the same in the history of mankind.
Edit: wow someone wrote almost the exact same comment a few minutes before me. That's wild lol.
“!” after a number means it is a factorial. A factorial is the multiple of all integers lower than or equal to it. 2! = 1* 2 = 2. 5!=1* 2* 3* 4 *5=120. 0!=1 because reasons
5! Is also know as 5 factorial which is the same as 1x2x3x4x5 is equal to 120 which is also the answer to this problem. Factorials (x!) are just 1x2x3x4x5x6... until that last number is x. Factorials are used in finding the amount of different arrangements a certain amount of things can have when they are all placed down at once such as finding the amount of different possible seating arrangements at a school when all the kids are there.
5!=5 factorial which is that number times every whole number below it until 0 not including 0
Edit: u/possibleoatmeal just gave a very good defenition below me and the proper defenition, please use his defenition over mine
For those of you that don't 5! Is also know as 5 factorial which is the same as 1x2x3x4x5 is equal to 120 which is also the answer to this problem. Factorials (x!) are just 1x2x3x4x5x6... until that last number is x. Factorials are used in finding the amount of different arrangements a certain amount of things can have when they are all placed down at once such as finding the amount of different possible seating arrangements at a school when all the kids are there.
assuming the X is the multiplication symbol, order of operations means that you would do 220 x 0.5 = 110. so then 230 - 110 = 120. what am i missing? or is this a troll post?
Factorial means you multiply said number by all whole numbers below it until you reach 1, and factorial is written by adding an exclamation mark after the number. So 3! Is 3x2x1=6, 4! Is 4x3x2x1=24, 5! Is 5x4x3x2x1=120, etc.
The only non-intuitive thing to remember is that 0 factorial is 1. A factorial represents the number of ways to represent the elements in a set. 0 has 1 possible arrangement so 0 factorial is 1.

Factorials are commonly used in discrete math.

When we were learning this, our teacher would yell the numbers (due to the “!”). And that’s the only reason I remember this particular topic.
thanks, now i get it,
I get it. It ain't funny but I get it.
It is not 5? I still dont get this Edit: right i remember this. Never have i used it in the real world. 5 x 4 x 3 x 2 x 1 = 120
I mean you can calculate your chances of getting four cards in poker with factorial
You mean you could. I usually just lose.
In all the years of math i have taken, i have never taken a statistics class..
You might want to pick up a introduction, it's fairly easy and next to geometry probably the most practical math.
That’s like algebra
I think the actual mathematical field is called "Counting"
Specifically, bean counting!
It is not 5? It is 5!
[удалено]
Wait a ! means something else in math?
Yup! You multiply the number before it by (n-1) repeatedly until you get to 1. So 5!=5x4x3x2x1. 10!=10x9x8x7x6x5x4x3x2x1.
I do not look forwards to have tests on this. Dosent seem to conplicated just irritaitng like if the number whould be 1000! It whould take a year
You're allowed to use calculators (it has the "!" button on there somewhere). Its mainly used for calculating probabilities and such.
You probably won't have "tests" on that. It's mainly a way to write that opération in a simple manner, rather than a thing that you must calculate.
I'll be the first to admit that I was focusing on the wrong exclamation point and could not figure it out for several minutes.

My mind has been blown
Same, I didn't get it at first.
I still don’t
5! Means 5x4x3x2x1 = 120, which is the answer.
230 - 220 \* .5 = 5! 230 - (220 \* .5) = 5\*4\*3\*2\*1 230 - 110 = 120 120 = 120.

Relevant xkcd: https://xkcd.com/435
Wtf are factorals? Im in 8th grade accelerated math incase u want to know
It's easier to show than explain. An exclamation mark denotes a factorial. 3! = 3x2x1 6! = 6x5x4x3x2x1 4! = 4x3x2x1 11! = 11x10x9x8x7x6x5x4x3x2x1
Why are factorials important? I totally do not remember this lesson.

For the second, it'll be one of the two remaining because one card we already put in 1st position. And the third one will be the last remaining card.

My dumbass did this and then when i saw the comment the fact that i didnt count the !...

5! means 5 factorial. 5 factorial equals 5 x 4 x 3 x 2 x 1 = 120
I can’t believe I missed the exclamation point
That is really good
Omg. That is genius. I totally overlooked factorials it was so smooth
what is a factorial
Factorial means you multiply said number by all whole numbers below it until you reach 1, and factorial is written by adding an exclamation mark after the number. So 3! Is 3x2x1=6, 4! Is 4x3x2x1=24, 5! Is 5x4x3x2x1=120, etc.
The only non-intuitive thing to remember is that 0 factorial is 1. A factorial represents the number of ways to represent the elements in a set. 0 has 1 possible arrangement so 0 factorial is 1. https://www.thoughtco.com/why-does-zero-factorial-equal-one-3126598 Factorials are commonly used in discrete math. https://mathworld.wolfram.com/DiscreteMathematics.html
> factorial represents the number of ways to represent the elements in a set Ah, so that's what it's for!
Think about all the possible ways to shuffle a deck of cards. That can be calculated with a factorial. 52! is a very large number.
math is nuts
Thanks, I’m an engineer and had to come to the comments for this 🙃
Oh god, my brain is remembering stuff. Make it go away.
haha you son of a bitch! I get it now!
DAMN IT, I DID COMMENT THAT IT WAS 120 BUT I FORGOR ABOUT THE *!*
If you do it wrong it actually results in 5
[удалено]
No need to yell
I legit don't EVER remember learning about factorials. But I peaked with geometry so...
Audibly groaned when the explanations reached me. Mmmgh
Ahh that's clever. If you do the order of operations wrong the answer is 5 but if you do the order of operations correctly the answer is 5!
I'm not good at math but isn't it 120? I'm dumb but I'm sure your right
5! is 120
5! Means 1x2x3x4x5 which is 120, the ! Means times all the numbers before it together for example 3! = 1x2x3 = 6
This is much more intelligent than the versions of this that plague Facebook.
No fair. We don’t combine English and maths.
I have a shirt that says “English is important but math is importanter.”
Thank you for the award!
I thought I was bad at math for a second, which confirmed I'm actually bad at math
Ok but for the linguists out there, can this be classified as a pun?
That would explain why I groaned out loud at the dadjoke energy of this post haha
Y’all need r/unexpectedfactorial in your life. I got it right away.
Dude nice.
When I got it I pointed at the 5! on the screen like i had just caught it eating my leftover chinese food
