I don't go to class anymore.... 3 hours of my teacher talking can't teach me what you could in 5 minutes. THANK YOU
True 😅 im drop out math class and just listen to his explanation
Joshua saving lives out here. Thats is simply the best and the easiest explanation. Thank you sir
Legend! Your teaching is perfectly paced and makes everything clear to understand. Thank you.
How i wish i had discovered this earlier .It has made life so easy.God bless you Joshua!!! some pple are just so Intelligent.Keep the good works up and am now a pro at this great!

I LITERALLY UNDERSTOOD A 3HR LECT IN 5 MINS TT THANK YOU FOR SAVING MY LIFE 🥲🥲🥲
Thanks so much for explaining how you picked the random number for the optimal point 👌 I never knew what was the right number but you telling me to multiply the coefficients of X and Y is GENIUS.
You're welcome!
Yes Joshua, you're awesome!!! This is what I call a Very Beautiful and Didactic Explanation!!! Thank You Very Much and GOD BLESS YOU!!! Congrats!!!
Extremely helpful short video!
Thank you very much for making it
That is simple, best and easiest explanation. Thank you for your help.
This was easy to understand! Well done! Thanks!
Tomorrow I have an exam and this was very helpfull. Thank you so much :)
Short and sweet. Nice for me to refresh those memories.
Great work Joshua! I have my Operations Research exam tomorrow and I am going through your videos to pass it. :D
LOOK WHO'S HERE!!! I have mine in 15 Days, and I'm here to learn the method to get coordinate of point B. BTW Thanks for videos and Day in life series, it motivates me to keep pushing forward to enjoy that good stuff I see in your videos ;) I'm applying for Winter 2021 intake once my exams are finished.
This is perfect. Thank you so much Joshua.

Thank you so much my professor. You saved my life.
Thank u so much for this im currently doing ACCA now and this helps me a lot in my f5 paper so thank u so much sir😊
thanks a lot. this is the best tutorial on linear programming.
Thank you soo much Joshua. You have a gift and its beautiful.
You are giving the best tutorial from you i can developed more knowledge thank you
This is awesome..keep up wherever you are
This was so helpful, thank you!
Thank you very much Mr. Emma :)

You are a life saver sir!! Thank you so much.much love
Thank u very much. I could understand clearly.
Its great 👍,keep it & sky is the limit...
شكراً لك جوشوا .. اختصار رائع . كنت أبحث عن أمثلة لحل المشكلات الحياتية مع الناس من خلال هذا العلم !! أظن أنه يمكن ذلك أو قد يكون مستخدماً في حل النزاعات بين الشركات
You are my best friend. Thank you. Very much appreciated
Thank you so much sir. It really helped me understand it better!!! Appreciate your help.
You're welcome, Alex.
Thank you so much for this video, it helps a lot!
this is the best explanation ... thank you very much
Simple and easy, Thank you it helped me alot
j'adore votre facon d'expliquer les maths. Vous etes clair, précis et bref. Merci.
De rien, Johanne. Merci d'avoir pris le temps de laisser une note.
awesome... I got clear concept... thank u for that....
That was really helpful. Thank you!
thank you for your effort, it is really helpful.
Sir Joshua, you have the same name as me but you're so intelligent! This is so easy to understand and I hope that it will help me on my OR class. Thank you ^_^
Your teaching is amazing . Thanks a lot!

Really good to understand...thank you sir
this solved my confusion
thanks... 💖
Good work sir
Tomorrow is our final exam in management science, thanks to you I will pass it.
thanks for the video, it's a really good one.
you’re amazing thank you so much!
Best teacher frrrr
Best explanation so far
Thanks, Joshua!
you should have at least 1 million subscribers
Hi, I really liked this video but I have one question. If you want to convert this problem from minimisation to maximisation, this suggests we move the objective function line (the hyperplane) in the opposite direction, but would this suggest there is no optimal solution to the maximise problem? (That's because the objective line would intersect two vertices/corners/extreme points at once.) Thanks
Thank you so much for this!🤍
انت برنس ي سطه انقذتني عندي امتحان بكره :D
Thank you for saving my life!
You’re a life savior 🙏🙏
You are soooo helpful!🧡
Happy to help! Thank you.
Excellent! Thank you!
Amazing explanation ❤
This was amazing and very helpful, studying right now for my exam and was always confused with the >= &
es: y>=4
thank you Joshua!
You're AWESOME! Thank you!
Thank you so much... I solved my problems
Joshua, thanks so much for the step by step direction. I was wondering if you can create a video to demonstrate this in excel. I was able to plot constraints 1 and 2 in Excel but I am stuck in creating constraint 3. I am taking a MBA class and use very little excel in my current field of work so I must be missing something. Once again, thanks for the step by step direction. I found it more helpful than my $300 text book.
For Constraint 3, you can use X = 0, Y=4 for one point, and X = 8, Y = 4 for the other.
Note that the choice of X=8 for the 2nd point is arbitrary. Just make sure Y=4 for the 2 different X values and choose your X values as desired.
Thanks Joshu! It worked. Looking forward to seeing more of your videos.
Nice and clear!
Great easy to follow
thank u so much sir ......
Awesome explanation
Terrific!
How im i to thank u mr joshua 4 dis wonderful job.
Nice explaination,
thank you so much.helpful
What happens if the figures in the objective function is more than the figures inputed on the x and y rows
Good reaching
Great sir ...
Thanku for class
sir for preparing video which software are you using
thanks man...
Amazing!
Thank you sir
Awesome!
Thankyou so much
Most welcome 😊
it's good explanation
