Its a walk in the park once you understand the iteration. Most professors get embroiled in ...lets say other things or trying to sound smarter than is necessary. These are very, very simple equations.
@@n-da-bunka2650 Our professor confuses most students (at least during lecture where we do not have much time to think through) so we have to figure it out online ourselves lol
This is an extremely clear explanation, but there is a MISTAKE at 6:25 where you mistakenly divided by 3 instead of 4, getting 20/51 instead of 20/68=5/17. It seems spectacular to me that half a million people watched this video and not a single one bothered to check, so I might be wrong, please point out my mistake if that's the case.
Such a clear explanation!! I suddenly had to sub for a professor for this topic and had to refresh my knowledge on this. I realized I barely retained anything on this topic and the book just left me more confused. This video really helped! Thanks so much Meghan!
our professor knows absolutely nothing about this and i was very concerned about whether i’d be able to understand this ever. thank you so much, you just saved me!
the thing i m gonna say may not be relative to the course. ur voice is close to my grandma, it s soft and warm, i never thought i can hear it on youtube. thanks
minor error at 6:26 - column w in row 2 should become 5/17 not 20/51. This does not affect the final solution, but I had to check it when you said out loud "21 / 51" and then wrote "20 / 51"
All these Indian tutor videos of durations ranging from 30mins to above an hour, blabbering on and on about the same old memorized technique without any sort of explanations; and here this video is, just about 8mins and my mind is blown. Thank you very much! Much respect all the way from the land of spices. And turbans.
This bring back memories from my Intro to Quantitative Methods One and Operations Research courses when I was a Business student at Saint Mary's University during the mid 1990s.
I did Linear Programming during my Introduction to Quantitative Methods One (Management Science 205) and Operations Research (Management Science 306) courses when I was a Business student at Saint Mary's University during the mid 1990s. While my professors, Professor Suzanne Cottreau and Dr. Muhong Wang, taught me Linear Programming very well, watching this video was a refresher for me.
I wanted to thank you for explaining this, I was really struggling with this and my teacher and her notes were basically worthless. Your explanation was clear and concise and I appreciate you.
But if the number in the pivot column is negative, how am i gonna choose the pivot element? Since i want to look for the smallest, but can it be negative ?
please help me Bright furniture factory has two products table and chair. Each table sells for birr 27 uses birr 10 of raw materials and takes birr 14 of labor and overhead costs. Each chair sells for birr 21 uses birr9 of raw materials and takes birr 10 of overhead costs. Each table needs 2 hours finishing and 1 hours carpenter y.raw materials are unlimited but only 100 hours of finishing and 80 hours of carpentry are available each weak. Demand for chair is unlimited but at most 40 table can be sold each week.
why do you even bother writing the values in columns of u and w, if you don't even use them? Just a waste of time calculating those values. And choosing pivot column and row is also a waste of time. you have 3 equations and 3 unknowns, simple stuff.
I have watched several videos that were UpTo 30mins and still didn't understand. Before watching your video, I was skeptical because I asked myself I'd i didn't understand in long videos how much then in a short tutorial. But no, I was wrong. Thank you a lot Ma'am.
Dr Math, can you please please solve a problem where one of our constraints is negative ont he right side? For example: Min 3x1+x2 Constraints: x1+x2=8 x1,x2>=0 Please if anyone can solve this!
This is the first time i understood instead of repeating the method over and over again our professor is really good and he explains great but the method he used to calculate was somehow complex ......and instead of that....i understood the row operations here best just ......thank you ... This'll help me very much tomorrow in exams
Wow. That is so much different from what my teachers taught me here in India. And tbh this seems far more easier, intuitive and useful. IDK why do they have to complicate it so much. Thank you Meghan for sharing this one. I'm gonna subscribe.
I wish this woman good health, happiness and money, loved the explanation!
I wish same for you
that's awsome explanation
Forget this. I'll just be a stripper.
lmao
Was expecting some motivational stuff in the comments....did not disappoint.
Revolutionary... world's first AI stripper
Made my day
😁😁😁
This is spectacular! My professor spent hours making this insanely confusing, and you made it sound like a walk in the park!
🤣🤣🤣🤣🤣🤣🤣🤣

I noticed this aswell but wasn't sure cuz no one else said anything about it, thanks
Thank you man, You're a life saver. I have been wondering, where I was going wrong.
@@cedocedd8108 It's kind of crazy how noone out of so many people noticed
@@nexovec I had to recheck my workings twice.
Glad I wasn’t the only one that noticed it :) thanks for the clarification
I learned more about how to do this method in 7 minutes and 43 seconds than I did in an hour of hand-wavy lectures. Thank you very much.
I never really understand why university lectures can't be this good. They do it as their full-time profession, and they still suck at their job
You just made 6 hours worth of lectures into 7 min. Thank you for making me open my eyes!
hey can i ask a quick question'
I guess it doesn't matter since they get put to 0 anyway, but how'd you get 20/51 and 52/51 in the w column, please? I ended up with 5/17 and 13/17.
Chris Walker me too 👌🏽
same here.. she has the wrong values
Me too, I pretty sure she made a mistake. so much for youtube tutorials being perfectly correct.
Such a clear explanation!! I suddenly had to sub for a professor for this topic and had to refresh my knowledge on this. I realized I barely retained anything on this topic and the book just left me more confused. This video really helped! Thanks so much Meghan!
our professor knows absolutely nothing about this and i was very concerned about whether i’d be able to understand this ever. thank you so much, you just saved me!
I think there a mistake in the last step, when you pick R2 - 1/4 R1, w should be 5/17, not 20/51. Anyway, thanks for your video.
it doesn't matter as they become the zero factors
i dont really know why the hell still traditional universities exist ?! awesome explanation
Broooo
It was really helpful but I don't understand how did you get 20/51 in the last step because I got 5/17.
same here
@@naimhasyim7662 same here
same here, I'm pretty sure she made a mistake.
How did you get 20/51 in the last table?
i really need this answer specifically
5/17
the thing i m gonna say may not be relative to the course. ur voice is close to my grandma, it s soft and warm, i never thought i can hear it on youtube. thanks
there's one more thing ... in the last table, last line and in the fourth column, the value should be 13/17
Thanks for the great content! Minor mistake: It should be 20/68 instead of 20/51 and 52/68 instead of 52/51 in the last step.
How did I have to scroll this much to find this error reported
@@arhamshah3425 Finally, Same here. I've repeated the whole example twice.
Far more in depth and thorough explanation than my teacher on my course. Thank you.
minor error at 6:26 - column w in row 2 should become 5/17 not 20/51. This does not affect the final solution, but I had to check it when you said out loud "21 / 51" and then wrote "20 / 51"
clearest explanation in nearly 8 minutes! thanks!
Ma you’re just too smart and plain,I give you your flowers 😁
you just nailed what my lecturer couldn't make me understand clearly for hours in 7:43 mins. Thank you

most helpfull for energy economices student
May I know how you do the calculations of 1st and 3rd row which are 0,17/4,1,-3/4,0 and 51 (1st row) and 0,-11/4,0,5,4,1, and 45 (3rd row). Thank you
she did LCM
Thanks 👍👍☺️ i dont know why the lectures makes it more complicated and always RUclips saved us 🔥
Well understand, thanks for the best and simplest explanation.
You have no idea how much you’ve saved me, Thank you!
OK... So when finding the pivot row and you get a zero... Since you are in for the smallest number do you choose the zero as the pivot row or not
Very good! So helpful!!! thanks a lot!
This is a wonderful explanation.Thank you for this !
You made this easy in 7 minutes
My teacher took 45 minutes and was getting confused himself 😂
Thank you so much, that was helpful
This bring back memories from my Intro to Quantitative Methods One and Operations Research courses when I was a Business student at Saint Mary's University during the mid 1990s.
What about the situation you actually have to make sure (x, y, u, w, p) >= 0 ?? This example does not showcase how to handle the situation
I Don't even know how to express my gratitude....really appreciate your explanation
You are a god! You can explaiin better than my 4th year engineering management course! God bless you from Ottawa, Canada!

Same here. I think we need to send Ms. De Witt on tour and have her stand in for every teacher on the day they explain this, LOL.
truly a life saver! thank you
Thanks for saving my exam paper...
I have an exam in 2 weeks and this never made proper sense to me. Thank you so much!!!
Wonderful explanation👏👏👏, thank you!

It was extremely heplful. One think i dont get. How did we found the numbers on the thrid board 0 ,17/4, 1 , -3/4 etc
Does the "simplex method" sound like a misnome to anyone?
the way of solving this problem was like royal,i mean straight forward.I love you madam.
No clear ... to long steps betwee😮n ... be carefull ... I'm trying normal teach ...
My professor spent 1h30 minutes on a 7 minutes problem🤦♂️

at 6:27 shouldn't W = 5/17 and the rhs = 12? Every way I'm calculating it I can't get 20/51 and 6
everything ok except that ... don't should be 5/17 in cell, on second line and fourth column, exactly at 6:25?
abominio
Omgggg…. I just understood this in my first try…. My professor made it sound like rocket science lol
Thank You! Best explanation I found.
Thank you for sharing your knowledge with us. It is much appreciated.
Good explanation! Reading the same thing from book take hours and there's so much text to confuse you.
Watching it 9hrs before exam. Wish me luck
thank you so much it was really usefull for me
Am asking why didn't you use the smallest value between 12 and 9
Ma'am your video made this sum so simple to understand thanks a bunch 🤗

so bad explanation..very quick
it is working, nut i have no idea how it works

Hhhh 😊
The woman is a genius
Good explanation 🙏... Though some errors
thank you a lot, btw i like the way u speak
Sir, i have question. What if x=>40 and y=>25 insted of 0. Do we still not apply them into the question ? or how do we apply them ?
It sounds like you are asking for optimizing the minimum instead then?
Thank you very much.....very clear
I hope this women is doing well. Thank you!
clear and easy to understand. Thanks a lot
Thank you Ms. De Witt; you are quite good at this.
I appreciate this video so much🙏🙏🙏🙏🙏
i dont think 52/57 is correct.
What if you still have negatives in the bottom row
Best explanation ever. Thank You
This was so helpful, thank you
where you got 45 you are supposed to add to 36 to get 81
Good solution, but we didn't get to see the word question.
Thank Heavens for this video🙌🏼
Dr Math, can you please please solve a problem where one of our constraints is negative ont he right side? For example:
Min 3x1+x2
Constraints:
x1+x2=8
x1,x2>=0
Please if anyone can solve this!
Jesus! Amazing explanation!
I did this drawing just 3 tables tho😎
of all the videos i watched why did this one make the sense
This is the first time i understood instead of repeating the method over and over again our professor is really good and he explains great but the method he used to calculate was somehow complex ......and instead of that....i understood the row operations here best just ......thank you ...
