10!=10*9*8*7*6*5*4*3*2*1

  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.

    Much easier to start if you know there are 3600 seconds in an hour. 36 is 9×4 and 100 is 10×5×2. Then 24 hours is 8×3, and 6 weeks gives you 6×7 (hand gesture).

  Okay, but did he pronounce it as “Ten factorial”‽‽‽‽‽

      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.

    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 = 6
5! = 5*4*3*2*1 = 120
10! = 10*9*8*7*6*5*4*3*2*1 = 3,628,800

      3,628,800 seconds / 60 = 60,480 minutes
      1008 hours
      42 days
      6 weeks

      10! means ten factorial. So 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1.

      It’s a common math joke.

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

  You’re missing 200 seconds.

    Am I missing something or just dumb? I did the math and 10! came out to 6 weeks exactly…

      You’re right, I fucked up.
