    Thank you so much for sharing this video! I'm taking a Finite Math course this summer, and the professor only taught us to do it by hand. I learned it, but it's so time-consuming. Knowing how to do this in 30 seconds rather than 10 minutes is such a blessing! God bless you, sir!

    Linear Algebra is one of those topics that is super easy to learn but just insanely tedious. When you are able to throw these problems into a machine (calculator) you eliminate the chance of simple addition and multiplication error and you save tons of time.
    I try to focus more on learning the concepts of linear algebra rather than becoming an expert of doing it by hand. Knowing the concepts has proved far more helpful in my engineering degree.

    I'm about to take my linear algebra final. You saved my life. I wish that I knew about this earlier

    We've been using an online RREF program, but we obviously can't use that on the exam. Thanks for the straight-to-the-point video, Mario!

    Very helpful. It's important to know how to do ref and rref by hand but for me personally it take a lot of trial and error. The calculator makes it such a breeze.

    Why can I only view the first 5 chapters? I would very much like to see the last 3 as this seems very informative. At around 2:07 it just stops right in the middle of a sentence. I can see that it is really 3:19 long.

    Will there ever be more than 2 numbers in each row while viewing the solution.

    • @jaredgarcia4597
      @jaredgarcia4597 4 ปีที่แล้ว

      Connor Stoyer yes, in this case the 3x3 that makes up the zeros and ones is called an identity matrix....this means there is ONE unique solution. If anything else is here, it can mean infinitely any or no solutions.

    Does the calculator always work with "augmented matrices?" Is that automatic?

      Hmm that’s interesting Vishal. Do you have a ti-84? Make sure you are using the negative key and not the minus sign.

    how do I switch the equation into a fraction

    • @MariosMathTutoring
      @MariosMathTutoring  5 ปีที่แล้ว +3

      Xina, I think you are asking about pressing the. ‘Math’ key then pressing the ‘frac’ key. Hope that helps!

  • @kotooriiii

    How do I know if the matrix has no solution, will it tell me?

    • @MariosMathTutoring
      @MariosMathTutoring  5 ปีที่แล้ว +5

      One thing that can happen Carlos is that one of the rows will be something like 0 0 0 3 or 0 0 0 And then a constant which tells you there is no solution.
