      1. It's a joke
      2. The comment was posted about a year ago
      Edit: There was a previous comment I was replying to that was talking about how Hank was "disrespecting teachers." The comment was deleted recently, so my comment may look like it has a different meaning. Just wanted to clear this up.

    I’m teaching myself algebra to study for an electrician test. I find myself watching these videos over thousands of others because you explain everything so good. I have adhd and have a hard time paying attention to things, but I think the combination of they way you break everything down with the different colors really keeps my attention and I’m able to grasp all these math concepts. Plus I enjoy your voice. It’s very soothing. Lol thanks man!

    • @anushkars
      @anushkars 7 років тому +2

      Kawther Alqallaf It can be written as +8 -(8) . So the negative 8 cancels out the positive 8 and results in zero

    • @typo691
      @typo691 7 років тому +1

      You're almost correct though. -(-8)+8=16 (notice the first minus)

    • @darkestone3016
      @darkestone3016 7 років тому +1

      Kawther Alqallaf no its zero

    • @darkestone3016
      @darkestone3016 7 років тому

      because. think of it this way on the number line is -8 so if you add 8 to negative the negative is getting greater resulting in the answer being zero. Hope I was helpful😇
