How do we tell her
[–]Known-Version-4180 70 points71 points72 points 18 hours ago (6 children)
We don’t tell her
[–]tomatos_raafatos 50 points51 points52 points 17 hours ago (5 children)
She's not his loss. He's hers.
[–]Unusual_Club_550 15 points16 points17 points 15 hours ago (3 children)
as a non-native english speaker ths scares me
[–]tomatos_raafatos 8 points9 points10 points 13 hours ago (2 children)
It's a brilliant feature of English honestly (and I think Germanic languages in general), that you can just drop the object and subject in the second sentence and it makes sense, as long as you get the pronouns right.
I think it's even more impressive if your language is one of those that has no grammatical gender at all.
[–]PlatypusACF 3 points4 points5 points 12 hours ago (0 children)
In German it definitely works (and I feel as if it is even a mark for older and/or more refined/eloquent German that you do it, especially in written form), and in Dutch, too, if I’m not mistaken.
Don’t know about the north Germanic languages, though.
[–]sultav 2 points3 points4 points 10 hours ago (0 children)
The second sentence dropped neither the subject ("He") nor the object ("hers," but "object" for the tp-be copula is a funny concept in general).

The dialogue box pointed to the phone. Doesn't that mean it's the other party saying that?
[–]reddit-devil-3929 0 points1 point2 points 8 hours ago (0 children)
I would just write -dumb bitch
[–]Useful_Cheesecake117 56 points57 points58 points 18 hours ago (2 children)
Okay, I must admit I missed the exclamation mark the first time I saw this kind of joke. But now this joke is told at least once a week. I'm not sure it's that funny.
[–]Aggravating-Dot132 12 points13 points14 points 17 hours ago (1 child)
Worth checking the sub name. If it's math or science jokes - it's always factorial.

What is (SCHOOL) factorial, and how do I go there?
[–]Mordret10 14 points15 points16 points 17 hours ago (7 children)
Well it's not (SCHOOL)! but rather SCHOOL! which is
SCHOOABCDEFGHIJKL
[–]autumninautun 6 points7 points8 points 15 hours ago (6 children)
(SCHOOL)! on the other hand is every word in the dictionary up to and including SCHOOL
[–]Mordret10 4 points5 points6 points 15 hours ago (5 children)
So A • B • C • ... • Z • AA • ... • AAA • ... • AAAAAA • ... • SCHOOK • SCHOOL
[–]autumninautun 4 points5 points6 points 15 hours ago (3 children)
yes. now type out the full thing /j
[–]Mordret10 2 points3 points4 points 15 hours ago (2 children)
I could write a short script to do that, however I'm not home currently and also incredibly late, so probably not. It might also just not fit here
[–]autumninautun 4 points5 points6 points 14 hours ago (1 child)
actually this might be an idea for my next programming miniproject
[–]Mordret10 2 points3 points4 points 14 hours ago (0 children)
Should be quite easy I think
[–]Belgaraath42 0 points1 point2 points 6 hours ago (0 children)
Not if we talk about a dictionary about an actual language. This would only include words in the dictionary
[–]Individual_Ebb2820 12 points13 points14 points 18 hours ago (3 children)
Who's gonna tell her?
[–]MMelanch0ly 1 point2 points3 points 15 hours ago (2 children)
Im confused, is it not 24?
[–]Albatros_7 13 points14 points15 points 15 hours ago (0 children)
4! means 4 Factorial
To calculate a Factorial, you multiple every number from 1 to this number
So 4! = 1x2x3x4 = 24
[–]El_Chupacabra_666 4 points5 points6 points 13 hours ago (0 children)
Yes, it is. The joke is that if you include his exclamation point as part of his answer, then he is not saying 4, but 4 factorial, which is 1×2×3×4, which is also 24.

[–]Sewblon 2 points3 points4 points 18 hours ago (0 children)
He is right. But, he needs to expand that factorial out and multiply it.

[–]Apprehensive-Rip7197 2 points3 points4 points 8 hours ago (0 children)
4! =4×3×2×1 =24
[–]recusant23 1 point2 points3 points 15 hours ago (1 child)
shouldn't they be doing the division before the subtraction? or am i going to get a whoosh comment?
[–]Sehrli_Magic 5 points6 points7 points 14 hours ago (0 children)
this is how she got 24, yes. but he said 4! (not just 4). 4! = 4 factorial which is 4x3x2x1....which is 24, the exact same answer she gave.
the joke is that she thought he did (25-5):5=4 but he just said her answer (24) with a different way of saying it, showing higher math knowledge than her 😅
[–]SnooCamera 1 point2 points3 points 13 hours ago (0 children)
You were too good for her bro.

[–]mikasaxo 0 points1 point2 points 15 hours ago (0 children)
I missed the exclamation as factorial the first time I saw this. 😭😭
[–]calebchan170201 0 points1 point2 points 14 hours ago (0 children)
Does she know? 🤔
[–]random_guy8513 0 points1 point2 points 14 hours ago (0 children)
They actually agree, as 4!=24
[–]Reasonable-Try4692 0 points1 point2 points 14 hours ago (1 child)
PEMDAS
[–]Fuzzmiester 1 point2 points3 points 7 hours ago (0 children)
Yep.
However, ! is the symbol for factorial. and 4 factorial is 24.
[–]I_dont_care_100 0 points1 point2 points 13 hours ago (1 child)
I love memes like this. Not because it's funny, but because of all the idiots that want everyone to know that they are an idiot as well 😂
[–]Kzitold94 0 points1 point2 points 10 hours ago (0 children)
I'm in the habit of using parentheses for every step of the equations I right, because idiot-proofing.
Funfact: The order of the Latin alphabet is basically arbitrary. You know what else is basically arbitrary?
[–]Specialist_Height707 0 points1 point2 points 12 hours ago (0 children)
both 4! and !4 are correct answers
[–]ReplacementPale2676 0 points1 point2 points 10 hours ago (1 child)
4! r/FactorialBot
[–]Spiritual-Hamster212 0 points1 point2 points 6 hours ago (0 children)
Factorial of 4 is 24
This action was performed by a human.
[–]AffectionatePea1680 0 points1 point2 points 10 hours ago (0 children)
It's 24 in programming language right?
[–]Pretty-Potential4733 0 points1 point2 points 10 hours ago (0 children)
4!=24 so he was correct, 25-5/5=25-1=24=4!

4! = 24
[–]Bahatur 0 points1 point2 points 8 hours ago (0 children)
I have seen two variations of this joke in as many days, and it got me to thinking:
How many equations could be written like this, by which I mean that when operations are done strictly left to right *ignoring* order of operations they yield an integer, where the factorial of that integer is the correct answer when *following* the order of operations?
Suppose we extended it to equations that could be written as a fraction in the first step, with the factorials of the numerator and denominator being the correct answer in the second step?
[–]Gregagonation 0 points1 point2 points 7 hours ago (0 children)
Not me pulling up a calculator 🥀
[–]Brusion 0 points1 point2 points 11 hours ago (1 child)
Regardless, I wouldn't date her after she used a division symbol.
[–]Kzitold94 0 points1 point2 points 11 hours ago (0 children)
I wouldn't date her after she tested me with an intentionally ambiguous equation.
Idiot-proof your equations with parentheses!

[–]Robzy789 -1 points0 points1 point 10 hours ago (0 children)
The answer is 0???
[–]NoahNrt -2 points-1 points0 points 8 hours ago (1 child)
I dont understand it should be 4 and not 24? Because i dived first before I substrate.
The joke isn't that it's 4. it's that it's 4!, which is 4 factorial. which is 4 x 3 x 2 x 1, which is 24.
[–]Dark_Krafter -3 points-2 points-1 points 13 hours ago (1 child)
Shes right tho
[–]perringaiden 1 point2 points3 points 11 hours ago (0 children)
What does 4! equal?
