    Weldon sir!
    Pleased sir, I need more clarity concerning the meaning and how to apply this “2cm to 1 unit or any other units." I don't really understand that part very well.
    I want to really know how it works so that I won't make mistakes when I am writing my Exams 🙏🏻.

      Dear Chuks, you should check the resolution with which you view the videos. Most likely, your device defaulted to a lower resolution. Set it to at least 720p and you'll see the difference

    • @DavetutsAcademy
      @DavetutsAcademy  3 ปีที่แล้ว

      Take -ve sign as you being a debtor to a bank. So, if you owe a thousand dollars, that's -1000.
      Now if you owe an insurance company nothing, that means you owe them 0 dollars.
      So, your total debt is 0-1000 which is still -1000 dollars.
      By the way, you can simplify stuffs by taking debts as negative numbers.
      Hope you get the gist

      But since 1_x is not possible how is 0_x possible

      @@tosinnathaniel8269
      Well... If I'm to answer this
      The reason why 0 - x is possible, and not compared to 1 - x will be because 0 could still mean 0x. So... We have:
      0x - 1x
      = (0 - 1)x
      = -1x
      = - x
      My own explanation though...

      But 0 doesn't mean 0x....I disagree with that, x means 1 only when you are adding it with a number with d constant x

    D scale you used can be confusing to youngsters,,, from box to box is 1cm,,, applying 2cm box to box,,, is not ideal......
