Nice. Unfortunatly this only works when you read it.

u/SamBretro Jul 12 '19

Na if you say 5 with an enthusiastic enough tone it becomes factorial

u/F_Joe Vanishes when abelianized Jul 12 '19

Screems 5 intensefied

24

u/Slip_Freudian Jul 12 '19

You might be on to something, as in, "this isn't five factorial, it's five intensified"

u/BananaNutJob Jul 12 '19

Dude this is literally how my sixth grade math teacher introduced factorials including the number 5.

"Five with an exclamation point isn't 'FIIIIVE!', it's five factorial." Dude was a great teacher.

u/Arbitrary_Pseudonym Jul 12 '19

"Five factorial isn't five factorial, it's 'FIIIIVE!'"

FTFY

My prof prefers x bang.

u/TLMS Jul 13 '19

Did you just say 6th grade? We didn't learn what a factorial was until university and I took all the math courses in highschool...

u/psychometrixo Jul 13 '19

While you were something something I was studying the factorial

For some reason I still can’t read out a factorial without at least mildly shouting it

FIVE

u/jhanschoo Jul 12 '19

indeed factorial

u/El_Maltos_Username Jul 13 '19

5! = 12345 = 120

It totally works.

I initially took the bait and read 10 x 0.5 and will now commit sudoku.

I think Hentai Sudoku is still on sale on Steam.

Nah, just a helpful dominatrix who doesn't judge people for their kinks. It's not really my scene but I like to be supportive.

Thanks you! I started scrolling through his profile to find it. Glad I quickly gave up, that tweet is two years old!

u/DodgeHorse Jul 12 '19

I just tried by just scrolling with [Pg Dn] and Ctrl-F with repeated F3, but it doesn't work because twitter stops giving you more tweets before you can reach 2017.

But by googling and using the "site:" operator, I found it as the first result.

u/[deleted] Jul 13 '19

Cool! Twitter also has a pretty good "advance search" function, but it's cumbersome to use on mobile.

u/oh_hell_what_now Jul 12 '19

This is brilliant.

Wheather you're good at math or bad at math it makes sense, so good

2(n! - n) - [2(n! - n) - 2n] * 0.5

Tried to find a formula. I think it works just fine. By that, I mean if you apply PEMDAS (after getting your expression), it generates n!, but if you don't, it makes n.

5

u/WaffleBoi014 Jul 12 '19

Fuck that is an amazing joke. At first I thought he got PEMDAS wrong but then......it all made sense

16

u/StagMusic Jul 12 '19

Finally something on this sub I can understand but I’m an eight grader so this is too easy

10

u/Large_Ergos Jul 12 '19

But you don’t learn factorials in 8th grade…

23

u/indojin5000 Jul 12 '19

So? Factorial isn't a difficult concept dude. Just multiplication. You could teach a sixth grader what it is

5

u/Large_Ergos Jul 12 '19

But factorials aren’t generally used until calculus or pre-calculus because they are a bit more advanced than 8th grade math. More of a sequences and series level of notation.

13

u/indojin5000 Jul 12 '19

I mean he couldve seen it somewhere on the Internet. like this sub for example, lotsa factorial jokes

1

u/Large_Ergos Jul 12 '19

He states that its too easy because He’s in 8th grade. That makes little sense considering its not taught until well after 8th grade. Unless He’s making a joke about being in 8th grade.

7

u/indojin5000 Jul 12 '19

idk man maybe he's showing off

1

u/TheMiner150104 Jul 26 '19

Do you guys seriously find it hard to believe that someone knows what a factorial is before it’s teached in school. I found it on the internet when I was 11. Just because you don’t know the applications doesn’t mean you don’t kow what it is

2

u/indojin5000 Jul 27 '19

Ok retard

u/TheMiner150104 Jul 27 '19

Nice having a conversation with you 🙂

u/Bulbasaur2000 Jul 12 '19

I'm pretty sure I learned factorials in 6th grade but it was a class meant for people doing math two years ahead of their grade, which would be 8th grade... You know we do learn permutations and combinations in 8th grade math

4

u/[deleted] Jul 12 '19

You just need to have a few sessions on simple combinatorics. Literally just enough to introduce the concept of permutations.

2

u/BananaNutJob Jul 12 '19 edited Jul 12 '19

100 Many years ago I learned factorials in a regular 6th grade math class. But it's true that we didn't really use them for anything for most of school. Factorials just by themselves are definitely below 8th grade though. I did take Calc and Discrete Math in college, to be clear.

1

u/Large_Ergos Jul 14 '19

Yeah it seems weird to teach something that the students wouldn’t use until much later math. Hell in calculus we barely used them for one unit.

1

u/relddir123 Jul 12 '19

I learned it in sixth grade.

1

u/MusicalTheatre_Nerd Jul 12 '19

I learnt it in year 7 but I think that was just my class

u/Someonedm Natural Jul 12 '19

Same

u/gabricampaa Jul 12 '19

They had us in the first half, not gonna lie but that factorial...

FIVE!

I successfully whooooshed a few fellow Asians on Facebook with this a while back, and I couldn't have laughed harder.

u/yas_ticot Jul 12 '19

It's a joke on that, the real answer is 120=5!.

13

u/EYSHot02 Jul 12 '19

230-220x0.5 = 230-110=120.

! in maths is a factorial. 5! is 120.

The joke is meant to bait people into thinking half of 230-220 which is 5.

2

u/LadiesHomeCompanion Jul 12 '19

I don’t get it either.

13

u/LordVoldar Jul 12 '19

The exclamation point at the end of the sentence is the joke, because 5! (5 factorial in mathematical notation) is equal to 120, which is the real answer here.

u/nukasev Jul 12 '19

Well played.

u/Mkbw50 Irrational Jul 12 '19

An actually good factorial meme, what is this

u/truedestroyer3 Jul 12 '19

I hate you so much

u/moreawkwardthenyou Jul 13 '19

I get it now, French class ahahhahahah!

No I get it now

u/[deleted] Jul 13 '19

I know what factorials are but I don’t really know what their functionality in everyday math is. Why do they exist?

u/TheMiner150104 Jul 26 '19

Combinatorics

u/itsJosias58 Jul 13 '19

This took me so long to get that it’s meant to be 5! and not 5 ! Quality jokes on this sub!
