    But then I realized the answer was actually "50" due to Bright Side.

  7. For the first question I didnt do it the way people always do it. I took 30 and turned it into 30/2 then simplified it to 15/1 then took the 15 and add 10 = 25 QUICK MATH

    7 seconds pass.
    Now we know 4 mins are left in the big glass
    When that is empty it means 11 minutes have pasesd wtf is this logic lmao…
    Since we flip it 4+the remaining 7 no matter how u look at it if im wrong then 7+7 is not 15
    7+4 is not 15..
    If we say big glass 7 mins,we flip
    Remaing in small glass,3
    Big one restart
    When small end 7+3=10
    We watch big glass near half empty we get 5 or 6 depending how good we see
    So 15 16 when we judge by our eyes
    And not deal with math lmao

  20. For the hourglass riddle, let's see.
    You have a 7 minute timer and an 11 minute timer.
    When the 7 minute timer runs out, the 11 minute timer has 4 minutes left, as 7 minutes are taken out.
    If you then turn the 11 minute timer upside down, the 7 minutes worth of sand that fell to the bottom, will now be at the top. Which means that the same 7 minutes of sand will fall again.
    Meanwhile, if you turn the 7 minute timer upside down, those same 7 minutes will fall.
    Therefore, 7 + 7 = 14.

    It's simple. If the two hourglasses are running for 7 minutes and they are both turned over at the same time, the same 7 minutes that fell, will then fall again.

    How should it be done?
    Like this.
    I'm going to represent the hourglasses as H1 and H2
    H1=7+0 (7 is the remaining time, and 0 is the time taken), and H2=11+0 (11 is remaining time, 0 is time taken)
    After every minute, we should get:
    1 minute: H1=6+1, H2=10+1
    2 minutes: H1=5+2, H2=9+2
    3 minutes: H1=4+3, H2=8+3
    4 minutes: H1=3+4, H2=7+4
    5 minutes: H1=2+5, H2=6+5
    6 minutes: H1=1+6, H2=5+6
    7 minutes: H1=0+7, H2=4+7

    So far, 7 minutes have passed, and now H1 is now empty, but H2 still has 4 minutes left.
    Now flip H1 over, but don't touch H2.
    7 minutes: H1=7+0, H2=4+7
    8 minutes: H1=6+1, H2=3+8
    9 minutes: H1=5+2, H2=2+9
    10 minutes: H1=4+3, H2=1+10
    11 minutes: H1=3+4, H2=0+11

    So far, 11 minutes have passed, and therefore, H2 is now empty.
    Additionally, 4 extra minutes had passed from when he flipped H1.
    That means 4 minutes of sand fell in H1. Now flip that H1 over again, but again, don't touch H2.
    11 minutes: H1=4+3, H2=0+11
    12 minutes: H1=3+4, H2=0+11
    13 minutes: H1=2+5, H2=0+11
    14 minutes: H1=1+6, H2=0+11
    15 minutes: H1=0+7, H2=0+11

    In summary…

    Start both 7 minute and 11 minute timers.
    After 7 minutes, turn the 7 minute timer over, but don't turn the 11 minute timer over.
    After the remaining 4 minutes of the 11 timer has passed, there will 4 minutes of sand in the 7 minute timer
    Now flip the 7 minute timer again to get those 4 minutes back.

    That is to say… 11 – 7 = 4, then 4 + 7 = 11, then 11 + 4 = 15…. or something.

  21. 3:27 he didn’t say the line had to be vertical or horizontal? He also didn’t say they had to be equal he said it had to be fine, so I just used my like to make the = sign be a ≠ sign. Technically it isn’t wrong

  22. Your hourglass problem is incorrect.

    The correct answer is :

    1. Start both hourglasses (don't start the eggs)
    2. When the 7 runs out, start your eggs, and flip the 11
    3. When the 11 runs out (4 mins cooking so far) flip it
    4. When the 11 runs out, stop your eggs ( 4+11 = 15 mins cooking total)

  23. Why 1+9+8=1… because you're stupid😏
