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.
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.
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.
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.
Bro I’ve been stressed out on a question bc I forgot how to put in in the calculator, but thx to ur vid I’m saved

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!
Thank you so much for this video, it has been the only one so far to be able to tell me what i needed!
Thanks Mario, as always really straight forward!
Glad you liked the video Alexander!
yesssss thankssssss its been over a month and my teacher skips that part everytime and he does it by head and doesnt know how to on the calc!
Saammeeee! Some people should really not be teachers
GOD BLESS YOU, YOU SAVED NY LIFE FROM A BAD LOOK FROM MY TEACHER
watching this the week before finals, i cannot believe how easy this was. I'm kicking myself for not googling this sooner, damn
Oh my god you just saved my life 😭😭😭 thank you
This guy came in clutch thanks 😌👍🏽
best video in youtube

Very helpful. Thank you!
Thank you so much. What a time saver!
You’re welcome! Glad my video helped you!
Omgggggg. Thank you from Germany

very helpful
you are my hero
Glad you like my videos!
what would I type if one of the Y's was (2/y) ?
Thank you so much!!!!!
How did you put the negative sign i tried to that and it didn't work
omg thx sm finally
You’re welcome Marwa!
Thank you.
Will there ever be more than 2 numbers in each row while viewing the solution.
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?
Thank you!
I cant put negative values in the matrix in my calculator ,pls help exam on monday
Hmm that’s interesting Vishal. Do you have a ti-84? Make sure you are using the negative key and not the minus sign.
Good vid! This helped a lot!
Glad my video helped you!
a godsend!!!
Thank you
You’re welcome Sarah!
thanks man
Any time
thank you sm
genuinely saved me 😅😅😅
Happy to help
ty
how do I switch the equation into a fraction
Xina, I think you are asking about pressing the. ‘Math’ key then pressing the ‘frac’ key. Hope that helps!
How do I know if the matrix has no solution, will it tell me?
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.
@@MariosMathTutoring thank you
