    In 3 minutes and 40 seconds you explained this better than my high school math teacher could've done in months back in the day. Just speaks volumes of your competency or her incompetency. I needed closure, thank you.

      @@jursamaj naaahh, I left out that part because I wasn't a problem. The whole class struggled to understand wtf the teacher was talking about, and we were in a math high school (Second Gymnasium in Sarajevo). The other teachers adopted this with ease. Now there's no way anyone could tell me that 32 people didn't understand anything because it was their fault. Not a single one. If there were 3 of us who got it I would admit that it was due to my incompetence.

    • @brycerothschadl
      @brycerothschadl 3 года назад +2

      c^p == true only when c == true and p == true.
      If both are false, then c^p is false.
      "AND" doesn't check to see if both values are equal to one another, it checks to see if both values are true.

    What about logical contradictions that are self-resolving? Self-resolving contradictions are tautologies too. Ex: the universe stays the same/the universe changes. Those are both true contradictions.

    • @gamerdio2503
      @gamerdio2503 4 года назад

      The universe stays the same is a contradiction because its expanding. It's not true. The other is a tautology because the universe is indeed always changing because of expansion. Its not a contradiction
