      must not a field have a propert that x*y means adding x+x+x...x y - times, or it can be different?

      Hello, can you please tell me how to translate equations like (x^2+5x+6=0) into a math field? I tried looking up that in ANY way, but I've been having no luck finding a way. 😓😣😢

      when i took abstract we did not study rings, integral domains or fields in class, were just given 3 pdfs that we were to study before the final exam

    My problem with abstract algebra has always been intuition, which most professors and videos on the internet skip. I've been through many videos of Socratica's abstract algebra playlist and my basics are so much better! You've given me a simple intuitive approach that I can easily build upon with my textbooks. Special mention to this video, it's eye opening. Thanks for clearing the fog and making abstract ideas so comprehensible. This is rare, keep going, lots of love and gratitude 🙌🏻❤️✨

    • @cadaankaa
      @cadaankaa 11 місяців тому

      Totally true. So many resources won't even through a single bone to help intuition. It's definition/proof, barely alluding to novel examples. Throwing in integers mod P in this video really turbo-charged the intuition factor.

    I like that your teaching videos are short and snappy. I’m extending my maths beyond the applied stuff I learned when studying electronic engineering decades ago. Purely out of whimsical interest and I get a bit addicted to it.

  • @spiderjuice9874
    @spiderjuice9874 5 років тому +3

    I'm building a computer and get to choose what instructions it will perform. While watching this video, I realised that I could free up 'space' for one extra instruction (a useful one that previously could not be included) by deleting all of the subtraction-based instructions and instead implementing negation-based instructions to go along with the pre-existing addition-based ones. In effect, I can do everything I could do before, and also got a bonus instruction into the bargain! I just have to perform subtractions in 2 steps instead of 1:
    1) negate B
    2) add A,B
    Credit where it's due: I had the thought to do this when you spoke about additive inverses, so thank you :)

    I thought I found some very good resources over the years, but I am amazed at how I didn't come across Socratica until now. This is the first video of theirs that I have ever seen, and everything from the clear explanation and clean presentation to the really satisfying sound effects is top-notch. I am thinking I may have just started another binge-watch tonight...

    It's worth noting that "division rings" do exist and aren't necessarily fields. As long as the multiplication is noncommutative, it will not be a field. But also commutative rings without multiplicative inverses aren't fields either. So really, they are both the distinguishing features between rings and fields.

    Very good explanation. I lost you in what exactly is the Char(F). Maybe it needed a little bit more explanation. Or maybe I should study Galois Theory xD

    • @mzg147
      @mzg147 5 років тому +4

      Char(F) is the smallest number of ones to be added in order for it to be zero. In Z/5Z, 1+1+1+1+1 (5 times) = 0

    is always a commutative group for any ring R. I think the video make a mistake at 5:26
    R^X is the set of the all units of R

    • @jiaminzhu406
      @jiaminzhu406 6 років тому

      I think we can define as for a ring R, if R^X = R\{0}, R is field.
      or we can define as for a ring R, if R\{0} is a group under *, R is a field.
