    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).

        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

          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.

        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.

        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
