I learnt more in this 5 min video on 1.5 speed than the entire cohort of my education trying to teach me.. thanks Joshua

[roderman]

I am almost positive i'll do 20% better on my exam tomorrow purely because of this video

[jackrdye]

This literally covers 9 lectures over the first 3 weeks of my 2nd year LP subject. It does it so much clearer too - Thank you :)

[andrewmoore]

I have taken two linear programming classes, watched countless videos, and read only knows how many lecture notes; your video is the first to clearly define and help me. Thank you so much!

[bjkocean]

The clearest explanation about slack variables. Thanks !

[bodgukalism]

7 year old video and you absolutely saved me from nightmares about this stuff! I appreciate you more than words can describe, have a blessed day!!

[AlanMichael]

My textbook introduced slack variables but didn't explain why (what they meant). THANK YOU! Makes total sense now.

Very clearly and concisely explained! Excellent review for my analytics class. And if you ever teach on diplomacy, I'm sure we will have world peace in a week. Everybody should subscribe to you just to support you as a teacher, even if they never watch again.

[pxosted]

it took my professor a week to explain what you have in a 5 minute video. god bless

[MrJayPuff]

Very good video, I wish my professor could have taught it this good.

My 3 credit course summed up in 5 mins. Unbelievable!

[zhongcharles]

The only commend I would make is: brilliant. Clear and explanatory, extremely helpful even without sound. Thank you so much.

[HelghastSon]

One of the most helpful videos on LP i've seen. Your voice is nothing short of soothing and enjoyable to listen to. Thanks!

[FPrimeHD]

You are one of the easiest people to understand and follow. Your LP series has helped me out tremendously. Thanks!

[kidanegebremariam]

I learned here 10 better than in class from the professor. Thank you Joshua

[mpangagadafi]

Thank you so much I have attended many classes of LP but I never understood anything but your video is the first I have understood.. Thanks so much

The real African Prince that I can truly count on. Never let me down with his explanation.
