Here here! Derek and his video series helped alter the course of my life for the better as well. There should be an award for UA-cam for people that make such a positive difference.
Funny you should say. I started watching his Python tutorials around 6 years ago. It radically improved my efficiency at work by writing a bot that basically automated about 60 percent of my job. My boss never did know how I did my job much faster than my coworkers. Then I got a job doing similar work for about twice the pay based on those skills.
As a self-taught Software Engineer - been at it for 10 years professionally now, and I am admittingly lacking in the Math Department. My journey began at learning Calculus, which quickly led me to realizing that I am not strong in Algebra. Long story short - I was looking for some no-nonsense, but very thorough, learning resources, and I can say that this series was all I needed other than just pure practice. Btw I am working my way towards Machine Learning, and I can also attest to the fact that ML is ALL math. If you don't know Algebra... you're not going to be learning ML :) Cheers!

Thank you Derek! I was preparating myself for aerospace engineering (even though I still have a long way to university). I made a playlist with some videos to help me preparate myself, and made it public, just so you know. Thank you a lot to let me learn all this content!
Beautiful! I've got my International Advanced Level (IAL) exam this year's May/June and your videos are helping me a lot. Looking forward to linear algebra and calculus videos!
Simple mistake at 5:55, but I'd like to address it: multiplying x by x gives you x^2. You would only get 2x if you combined like terms such as x + x. Other than that, great video! Very helpful!
Please keep doing these videos on math all the way through like you said. You are very easy to understand. That’s not very common. I’m reading a lot of books Tesla. Also stuff on magnetic fields. I can always understand the mechanics, but when the books get into the math, it gets real confusing and I believe your courses would really really help me. Thank you so much for doing this.
Ooh exactly legit fr irl imho @op. That is one of if not my favourite things about yt is it is like the internet fwiw ftw evne., full an fileld with so much abundance of learning/teaching video of many skills and a vast array of knowledge among the plethora of music videos/ytp's etc. That is ftw fr. My fav yt channels I feel teach me somewat in some way or another. Or that at least I can and have a desire for learning something fwiw I can take away from each video now.
Wow, your programming videos really helped me a lot over the years and now maths! Thank you very much! I am of course subscribed with notifications turned on and thumbs up!
Well Done Sir! I had to start over and set aside my Old notes. Taking new Notes now based on this Video. I have College in the Fall and Need to Test outta some Math Classes.... This is my before watching the whole Video....
@@steph7115 I got a 22 i believe. my highest scores were in english, reading, and science. im just bad at that and got a pretty low score on it. and i went to a little act workshop that helped
Thank you so much for this. I am going back to college and have to take Precalc 2 and it has been 4 years since I took Precalc 1 so I am very rusty. Hopefully 2 weeks can be enough time to prep
Hi Derk, Thanks for the math brush up, needed it to help out my kids. I follow your channel from 2008, amazing the amount of knowledge you poses. Keep it up mate.
Mistake at about 5:52 .... x times x isn't 2x is't x^2 ... at 1:10:10 your second step is technically not equal to the starting problem as he suggests it is, so even though he gets the correct final answer it's confusing....at 1:15:30 the second rule is wrong, the 2 should be an a..... at 1:32:25 he says 2 and 6 work and then proceeds to write a 2 and an 8, so it should be (x+2)(x+6).... I see now at 1:34:45 he corrected that last one after someone commented..... at 1:37:20 he says 2^2 when he meant to say 2^3. However he fixes it in the next step and gets the right answer...... at 1:39:00 he says (x-3x) when he meant (x-3)... then he gets the final answer wrong as he uses (x-3x) again... which is obviously wrong as it simplifies to -2x but he's clearly trying to get this done as fast as possible and not catching these things... and I think fatigue is setting in lol..... 2:16:40 I think this explanation of what makes the function even or odd is pretty confusing, especially since you said -x^2+2 is equal to (-x)^2+2.... this actually isn't true because in the first one only the x is squared but in the 2nd one the square is applied to the negative sign.... he makes a similar mistake in his explanation for the odd function that follows...and to say substitute a-x for your function isn't really helpful... didn't even explain what a is...honestly I didn't understand that sentence at all... I think maybe he meant to say that f(x) = f(-x) which would be the true definition of what makes a function even...but then he did say that shortly after.
hello there, you seem to know what you're talking about so i was just wondering at 56:54 (finished problem) i know that he shouldn't have dropped the negative from the 3 at the beginning, but how did he get l x + 2 l = -2 from 3 l x + 2 l = -6? i have no clue how 4 was just suddenly added to the equation. do you think you could just work me through the entire problem?
Actually after looking it over again, I realized that he did it correctly and removed that part of my comment.... he still didn't explain it very well as he hasn't in a lot of this video as he's just trying to go through everything really fast and so he isn't covering a lot of the details..... but let me re-write his steps adding one more in the middle to help explain how he got his final answer: 9-3lx+2l = 15 -3lx+2l =6 (after subtracting 9 from both sides.... he did this step and the next one in one step) 3lx+2l = -6 (he divided each side by -1... he just saw that there was a negative sign that he'd prefer on the other side so he intuitively moved it to the other side... I wouldn't have done it this way but nothing wrong with it) lx+2l =-2 (he divided by 3 on both sides) From here you can see it's no solution.... of matter what you plug in for x, lx+2l can't equal a negative number... x+2 could be positive or negative but either way lx+2l can't be negative.... I don't know why he wrote x+2=-2 at the end.... it looks like he was starting to go through the next step that you would take if it was an abosolute value problem with a solution but then realized that it wasn't nesasarry and just stopped.
Just took my first universty course in linear algebra, i figured out i had some problems with basic algebra. Amazing Refresh. Thanks alot from Israel !
Hello, I just have a question about 23:49 and if b = 1/4 or is added for 7/4 as when I attempted it it seemed liked -3/4 I am just reviewing for a new algebra two course I’m take but your videos are super helpful
I would love to have all your notes on paper so I can 'play' with them anywhere at anytime when I need to relax! I can't continue watching now as it is 11.47pm, 18.8.24, and I've just had a week of very late nights at Broadstairs Folk Week BUT I really wish I'd found you at 6 o'clock this morning so I could have played with algebra all day! Jeni
Thank you for this video... One of the best video for mathematics... Totally high school basic but thoroughly explained... Please ping here your machine learning playlist.. unable to find..
27:00 The worst thing you could do in Algebra is to memorize formulas without understanding, if you can understand the math you can just derive them, so they make sense to you and therefore never forget them. The formula shown in the video for example is derived from the Pythagoras theorem, so no need to memorize it. 37:00 in this case for example we could explain why we are even to do this to begin with adding 2 linear equatuons, instead of trying to memorize some seemingly arbitrary procedure.
Method 1) (- x= 6) equation is given Multiplying both sides by (-1) -1*-x= -1*6 Then x= -6 or Method 2) Let the equation be (- x= 6) If we multiply both sides with "MINUS" sign -(- x)= -(6) Then x= -6. Which one method is correct or both methods are correct Please help 🙏🙏
34:11 you forgot to flip the > when multiply by minus so its x < 6 and not x > 6 it was easier to just leave the 2 in his place and move the -1/3 to the other side
Thank you so much. I am taking an electrical engineering career training high school class. The prerequisite is a minimum of a c in algebra. I was never good at algebra. This should hopefully help.
I'm happy I could help. This is basically one example for most anything you'll ever see in Algebra 1 and 2. If you can solve them on your own after watching this you'll get an A on every algebra test
@@derekbanas So if I can Solve the Algebra 2 Questions on my own after watching this, I'll be alright during tests? I'm a Sophomore in highschool taking it and I am really struggling with this. So if I do the problems by myself I'll pretty much know like 80% of Algebra 2?
Since he was going so fast, he didn't repeat that the original question was to find a line *parallel* to x - 4y = 1 that intersects a point of (-3, 1). That means he had to, first, find "m", the slope of his line, which will be the same for the parallel line, and then find "b", the offset up or down the y-axis for the parallel line. So with y = (1/4)x - 1/4, he had solved for "m", and then he could solve for "b" by plugging in his known values into y = mx + b. So taking y = mx + b, knowing that the slope is 1/4, and this parallel line intersects (-3 ,1), you would start with 1 = (1/4)(-3) + b. Now, he skipped a few steps with writing this out and instead just started with b = (4/4) + (3/4), to get b = 7/4, which without referring back to the original question, looks and sounds confusing, but it means the parallel line is y = 1/4x + 7/4. I think he zipped just a little too fast there. This is a crash course mostly for people just refreshing themselves, but teachers should avoid doing steps in their heads while instructing.
Hello Sir Derek, May I ask for your advice? I'm having hard time learning frameworks. I tried learning flask, django, and currently laravel. I gave up on flask and django because I find them extremely difficult. Programming using these frameworks feels like I'm tied into a chair. I feel restricted and no freedom is given. Things such as classes, methods, requests, etc. are supposed to go into specific locations, and I find it difficult to memorize all of them. Have you experience these before? If so, how did you overcome it? Thank you.
Hello Mr. Banas, I hope this message finds you well. As a senior in high school preparing to start college this fall, I am planning to take college algebra and I was wondering if you know of any additional resources or tips that could help me prepare for the course. Thank you for the video!
I think two resources may help. The No-Nonsense Algebra books are good. I'd use them in combination with an app like Symbolab. Symbolab will take a picture of any problem and then explain step-by-step how to solve it. There are only so many different types of Algebra problems you will ever see. If you set them up and can solve all of the types you can solve them all. I did my best to provide one of any type in this video, but additional resources and problems always help.
Thanks for much for this video I'm a junior developer and just finished your algebra video What other videos or topics are there that would be most beneficial to my in your opinion ?
Maybe code some algebra topics like polynomial class and matrix class in C++ or C# including numerical eigenvalues calculation (QR method with shifts and deflation)

I'm confused, at 23:32, you claim that we must set x = 0 to easily find the y intercept. That's not how I did it. I would substitute "y = mx + b" with the values in the given point and the slope that we had found. It gives the same answer, being 1.75, but I don't get how you did it.

Then x= -6.
Which one method is correct or both methods are correct

wow man , this is the best revision of basics i could possibly hope for, +1 subcribeD :D
Thank you very much :)
34:11 you forgot to flip the > when multiply by minus so its x < 6 and not x > 6 it was easier to just leave the 2 in his place and move the -1/3 to the other side
at 5:50 x multiplied by x would be equal to x raised to the power 2

Factoring Trimials:
X^2 + 8x +12 = (x + 2) (x + 6)

So with y = (1/4)x - 1/4, he had solved for "m", and then he could solve for "b" by plugging in his known values into y = mx + b. So taking y = mx + b, knowing that the slope is 1/4, and this parallel line intersects (-3 ,1), you would start with 1 = (1/4)(-3) + b. Now, he skipped a few steps with writing this out and instead just started with b = (4/4) + (3/4), to get b = 7/4, which without referring back to the original question, looks and sounds confusing, but it means the parallel line is y = 1/4x + 7/4. I think he zipped just a little too fast there. This is a crash course mostly for people just refreshing themselves, but teachers should avoid doing steps in their heads while instructing.
@@ExterminatorElite This is the MVP comment right here
@@ExterminatorElite Thank you very much !
still need to work on my basics. wow. I got lot of climbing to do if im to follow this. im ready for the challenge... LETS GO!
5:52 typo, should be x^2
good to know you also have a video for trigonometry
God bless you, sir!
God bless you and your loved ones as well :)
24:08
I am little bit confused. Shouldn’t the y-intercept be -1/4 or am I missing something?
yeah i have the same problem currently cause im wondering where he got those numbers from
thank you mr banas. very good video and this feels like im being tutored. way better teacher than my current algebra teacher haha
It's 4am, i'm high af and last time i learned basic algebra was 6-7 years ago

Dude, I think you've saved my sophomore year.
Happy to help :)
Good day, Derek!🙏
Thank you :) I hope you have a good day as well
Geometry,Calculus,Economics please !
Trig for Calculus is coming this Thursday on Twitch and next Thursday on UA-cam. Then I'll move on to Calculus
and Finance and maybe accounting.
I’m planning to major in astrophysics so I definitely need to master math and science thanks for posting
Hello Sir Derek,
May I ask for your advice?
I'm having hard time learning frameworks. I tried learning flask, django, and currently laravel.
I gave up on flask and django because I find them extremely difficult.
Programming using these frameworks feels like I'm tied into a chair. I feel restricted and no freedom is given.
Things such as classes, methods, requests, etc. are supposed to go into specific locations, and I find it difficult to memorize all of them.
Have you experience these before? If so, how did you overcome it?
Thank you.
Learn from Durga Sir..He is God of Python....You will understand everything,,,just search on UA-cam:--Django by Durga sir
Check out 9-3!x+2!=15
Sorry I 've to use excamation for absolute.
Hello Mr. Banas, I hope this message finds you well. As a senior in high school preparing to start college this fall, I am planning to take college algebra and I was wondering if you know of any additional resources or tips that could help me prepare for the course. Thank you for the video!
I think two resources may help. The No-Nonsense Algebra books are good. I'd use them in combination with an app like Symbolab. Symbolab will take a picture of any problem and then explain step-by-step how to solve it. There are only so many different types of Algebra problems you will ever see. If you set them up and can solve all of the types you can solve them all. I did my best to provide one of any type in this video, but additional resources and problems always help.
@@derekbanastysm!
Hello, first of all thanks for the video. Could anyone tell me why the inequality was not fliped at 34:11 thanks alot.
He multiplied the inverse of -1/3 of which is -3/1 which is simply -3•(-1/3) = 1x hence no division was involved the “
Thanks for the help
2:05:00
thank you! can’t wait for the calculus video
….
Have you ever thought about doing shader programming here?
Thank you so much m8 :D
56:20 9-3 | x+2 | = 15 to -3| x+2 | = 6?
The videos are very excellent despite the few errors
Thanks for much for this video
I'm a junior developer and just finished your algebra video
What other videos or topics are there that would be most beneficial to my in your opinion ?
If you want to into Machine Leaning or Data scence then Trig, Pre calculus, calculus, linear algebra.
I worked out the problem and I don't see how you are getting b to equal 7/3 at minute mark 23:32. Can you explain in a little more detail? Thank you
Amazing video. New Sub
I want to learn more about calculus. I am still learning new things about pre - calculus
I’ll be covering calculus at some point this month
thanks!
Maybe code some algebra topics like polynomial class and matrix class in C++ or C# including numerical eigenvalues calculation (QR method with shifts and deflation)

X . X = X^2
Not 2x
However X + X = 2X
But thanks for the infos ❤
Hi Derek how do you record your videos on iPad? thanks
I stream the screen using AirServer on Windows to OBS
At minute 24, where did you get 3/4 from?
56:00 mistake here, there is a solution cuz the equation equals 2, not -2
Maybe it’s me but the way my teacher teach us is totally different from his way of teaching, I understand better coming from my teacher than his way
I'm confused, at 23:32, you claim that we must set x = 0 to easily find the y intercept.
That's not how I did it. I would substitute "y = mx + b" with the values in the given point and the slope that we had found. It gives the same answer, being 1.75, but I don't get how you did it.
