Jason, thank you so much! I’m 30 y/o dude studying school program because I was never properly taught, and you are a gifted educator that I never had... thank you, and God bless you and your family!❤️
I've been watching these algebra 2 vids for a week now, I'm halfway through. Trying to bone up on algebra before I teach myself precalc so I can test into Calculus. Wish me luck sir. Thank you for these vids these are a public service.
@@Kenzi1000 hey thanks for reaching out I wish you all the best. I recommend using some kind of interactive site like a khan academy for quizzing on these subjects. Jason's lecturing tho is top notch. I did test into calculus but decided to take precalc anyway. I am more than prepared. I just want to have even more rigorous knowledge.
@@LeFruFru glad to hear! I'm using Khan Academy, but I found some of the lessons a bit lacking when it comes to exponents and complex fractions. Good luck to you!
Thanks! I am re-learning all of this beacuase I dropped the ball a long time ago in high school. thank you so mucj! I couldn't learn it with just Khan academy.
Look how straight his lines of writing are, how straight (not wiggly, and not slanted) the lines as graphic elements are. Look how consistently spaced everything is, and how neither over-crowded nor scattered. Even some very good online teachers are less than optimal in this regard. I know that that is not the point, but it does suggest orderly thinking as well respect for the audience. Even with the sound off you would know that this is a true educator. (edit: He could make up his mind how to write "1". But still, what I said.)
Excellent training video, the first one solved many of my difficulties. I have been needing a solid explanation like the one provided in this video! Thank you for taking the time to go through the baby steps and explain, yes explain!
Every single 7th grader that is struggling with algebra should watch this video. This is really an excellent lesson. I would only add that manipulating regular numbers over and over with fractions in 5th grade etc...would only make this much easier. TU!
Omg, I can’t tell you how many videos I’ve watched trying to figure this out, and NONE of those videos explained it in a way that I could understand…UNTIL NOW!! Thank you so much for ACTUALLY explaining the whats and whys.
It's close to midnight and I'm at my go-to spot when the problems in the book aren't being explained where I feel confident I can execute them. Math and Science RU-vid Channel saves the day again !
Great Lesson. In the comments it is self evident that you are an excellent educator. Pair this with your generous gift of knowledge and you make the world better. Well done.
Thank you for this, I am almost done with my mah prereq Pre Algebra and introductory to Algebra. This is the only channel that I have gained a true understanding f what I need to do. I graduated back in 1996 with General Math. Both of my math teachers were not for me. I comprehend very well but with math I need some TLC and they didn't give me that time. I was not the kid that goofed off in class either that was the only class that I barely passed. Again thank you kindly!!!!!!:)
I am so glad I found your videos, you sure are very good at explaining " how to" I am refreshing so I can help my son who is doing virtual learning. Thank you Sir!
I found this extremely helpful, even though I’m not a part of your class. Can’t wait to for more. I wish I had this type of math material teaching when I was back in algebra classes. Makes it easier to understand.
Complex fractions are simply fractions divided by fractions. Let f(x) = a fraction(s) Let g(x) = a fraction(s) So, f(x)/g(x) is a complex fraction where g(x) cannot be 0.
On the third example it is better to use x and y as variables or a and v in place of u and v because you cannot simply identify on your hand writing which is which.
Mr professor thank you very much you let me understand a little bit of your explanation make me happy, thank very much I appreciated that may God bless you and your family ❤❤❤❤💯
V to minus two minus u to minus two can be factored to the sum of two squares. That leaves u to minus one plus v to minus one that equals v plus u over vu. Or one over v plus one over u.
@@MathAndScience can you explain why you could factor out the -1? Because i thought whatever you do to the denominator you have to do to the numerator? Why wasnt the numerator multiplied by -1 also?
@@dejarenee5864He didn't add anything new to the equation when he factored out the negative 1. Lets say you have negative 5 divided by 2; that is the exact same as (negative 1 times 5) divided 2. In other words, you only have to do it to top and bottom if you are adding a new number or new variable. Factoring out a negative doesnt add anything new, it just changes how it looks for convenience. Even simpler: (negative 5) is equal to (negative 1 times 5)
Thanks so much for your video. In the last problem, you canceled out the uv and the squares on the u sq'd times v sq'd, but how come you weren't able to do the same with v sq'd minus u sq'd and v-u? When I did this problem on my own, I ended up with v-u/uv instead of v+u/uv like you had.
I agree, His method of getting difference of two squares leave = v+u/uv but if you do what you're saying you get = v-u/uv which I am also confused with?
@@sammaths2324 I believe the subtraction sign of the other two terms disallow the factoring you mention. Only valid in this context with multiplied terms.
I just wanna ask about the part I don't understand. why is v²-u² from the numerator at the left side is not cancelled with the v-u from the denominator of the right side
Not bad but would be better without the rattle on that doesnt explain the solution to the problem. e.g. at 18:25 theres rattle on about students getting crazy mixed up etc which does nothing but to take the focus away from the problem solving aspect which in my mind at least then would cause a student to lose concentration on the problem at hand. Not a bad idea to explain wherer a student may get mixed up to another educator but the student doesnt need the focus taken away from the problem so often. Otherwise pretty good explanation.
