Fine, I'll do the math:
60 seconds in a minute (10 × 6)
60 minutes in an hour (9 × 5 × 4 / 3)
24 hours in a day (8 × 3)
7 days in a week (7)
6 weeks (3 × 2)
The bold 3's cancel out and become × 1, and then it's easy to see each integer from 1 to 10 appears exactly once when it's all multiplied together.

It took me way too long to understand the joke, I may be fucking dumb

I still don’t get it, so… you could be worse.

A number followed by an exclamation point means multiplying it by each whole number below it until one.
3! = 3*2*1 = 65! = 5*4*3*2*1 = 12010! = 10*9*8*7*6*5*4*3*2*1 = 3,628,8003,628,800 seconds / 60 = 60,480 minutes
1008 hours
42 days
6 weeks

6 Weeks * 7 days * 8 * 3 (24) hours * 2 * 4 * 5 * 9 * 10 (3600 = 60²) seconds
The last one is a bit of a jump, but 9 * 4 is 36 and 10 * 5 * 2 is 100 so together it's 3600.

Thank you!

10!means ten factorial. So 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1.It's a common math joke.

Me too. It’s even there in the title I didn’t read at first. I thought it was about them having just 10 seconds left.

It's not typeset correctly or it would have been obvious and ruined the joke.

Okay, but did he pronounce it as "Ten factorial"‽‽‽‽‽
genfood@feddit.org · 15 pts · 174d
Nah, he wrote it

It's like "there are 10 kinds of people in the world: those that can read binary, and those that can't."
It doesn't work if you say it aloud.

Okay, I tried the joke out. I said "it" out loud to my spouse and they didn't laugh.

seconds in an hour = 3600 = 10 * 9 * 8 * 5
24 hours in a day = 6 * 4
7 days in a week = 7
6 weeks = 6 = 3 * 2 * 1

Aw, you beat me to it! But I formatted it better. So who wins? :P

You're missing 200 seconds.
TommySoda@lemmy.world · 24 pts · 174d
Am I missing something or just dumb? I did the math and 10! came out to 6 weeks exactly...
remon@ani.social · 22 pts · 174d
You're right, I fucked up.
TommySoda@lemmy.world · 17 pts · 174d
It's okay I still love you. <3
