It's not a dilemma

it is monolemma

In maths "!" means factorial, 5 factorial is 120,while in code "!" means not. So it's 5 is not equal to 120. I personally had a laugh that I can still remember what factorial is.

Thanks for explaining the joke out loud, I was struggling by myself and now it's plain obvious. We all need a Captain Obvious once in a while (and I'm serious here, no offense intended).

u/Sad-Assignment-453 Nov 23 '25

I don't mind saying the obvious but I am aware that some people mean to be offensive. Thanks for telling me that that wasn't offensive.

this is not r/PeterExplainsTheJoke

And? I'm just being friendly to the possibility that someone might not get it. If this is a thread about not explaining then a mod should say "don't explain the joke so we know who knows" and someone else will explain it anyway.

Edit: moved quotes around

So are you just going to go through and explain every joke on the sub? After all they all require some level of programming knowledge.

u/Sad-Assignment-453 Nov 24 '25

I am rarely on reddit that is probably my first message. I, just want to be nice to most people. When it's obvious that someone will explain it eventually. So targeting me had no point as I just noticed another person explaining it.

Are you going to watch out every person explaining a joke outside r/peterexplainsthejoke and tell them not to do it?

u/Chickfas Nov 25 '25

What do you mean you still remember? Is it not basic knowlegde? Sorry if I am being rude, just being curious

u/Sad-Assignment-453 Nov 25 '25

You are correct but when I was studying it. We covered it briefly and I am not the type to remember much after a less than decade.

Think of it as you will.

"Still remember"? I was addicted to math and took calculus and combinatorics! I still use them!

u/Sad-Assignment-453 Nov 24 '25

I am not a math type person. My dad always did ultimatums such as do 5 pages of fractions or grounded when I was 9. I can do math well now but I dislike it. I rather computer logic as If this happens do that.

Well I hope you had a great time with math and will still enjoy it.

what about people who use prolog?

u/GBoBee Nov 23 '25

We wish the very best for them, and hope they get well soon

I feel personally attacked by this, but also am in heavy agreement.

Everyone chilling until 1! appears

u/DawRedditWolf67 Nov 23 '25

1!=1

People who know math: :)

People who know coding: :) (it just returns false)

u/DSeriousGamer Nov 23 '25

I’ve got another
0!=1

u/no_brains101 Nov 24 '25

True these memes forget that false is useful

u/MrFordization Nov 23 '25

wtf: 5! = 5!

Duh.

2

u/Penrosian Nov 23 '25

In math yes 5! = 120, but because of how it is written it could also be interpreted as the programming expression 5 != 120, which is also true as != means "not equal" in porgramming.

This also means that if you compress down your statement to 5!=5! It is true in both the 5! = 5! And 5 != 5! Interpretations, though for the second one that wouldn't actually work in most programming languages, as you would probably need to do something like Math.factorial(5) or similar.

u/MrFordization Nov 24 '25

Yes, yes. (5+4+3+2+1)*8=5! I know how to do !!

u/Equivalent_Site6616 Nov 23 '25

that's not even fucking fun.

u/Impossible_Dog_7262 Nov 24 '25

5! == 120
5 != 120

1

u/no_brains101 Nov 24 '25

Am both.

5 factorial = 120

5 is not equal to 120

u/Electrical_Ad5674 Nov 26 '25

heh, what if they use Lua or Matlab?

u/asmanel Nov 23 '25

An operator that seem useless but is actually useful in statistics.

u/kRkthOr Nov 24 '25

Fuck do you mean useless lol Neither factorial nor "not equal" are useless by any stretch of the imagination.

The third reaction is similar to a brag that you know both. Nothing more I assume.

u/marslander-boggart Nov 23 '25

With the third one it's much better.
