    Excellent video but I don't understand why the square brackets are needed?

      You can use either, when you already have a round pair, the square ones help to keep things straight.

    Can you give me another Long probLem Of Order Of Operations with aLot Operations Like mutipLication ,Division subtraction ,Addition and Exopents Long Order of Operations on the numerator and the demominator either May 30, 2023 0r May 31 , 2023 . And I’m taLking about the RUclips video you posted on your channeL (January 21 , 2023 ) . ActuaLLY EVERYDAY .

    HELP help Please. At the minute mark 10:53 please explain why the 24 is changed to a negative. in the problem
    = 4 - 12 x 2 + 9 = 4 + (-24) +9 HUH?? thanks for all your videos. You have helped me learn algebra at 54 while teaching a student at home. But this has got me lost. Thanks a bunch. Have a great day.

      This is how most people learn to subtract integers. The answer is the same either way.
      a - b = a + (-b)
      Example:
      5 - 4 = 5 + (-4) = 1
      Let's look at the problem at the starting point you gave of 10:53:
      4 - 12 * 2 + 9
      Method 1: Change over to addition of the opposite.
      4 + (-12) * 2 + 9 = 4 + (-24) + 9 = -20 + 9 = -11
      Method 2: Don't change the subtraction operation.
      4 - 12 * 2 + 9 = 4 - 24 + 9 = -20 + 9 = -11
      As you can see it's the same either way. I would note this is a series of video lessons with practice and it's best to do them in the proper order. Good luck!
