Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

dear algebra, dont ask me to find your x, she is not coming back and dont ask me y

dear math, I am not a therapist- solve your own problems

Hahahah
An 8 min video, it took my teacher a whole period to explain this
1➗85=
Mo 193 teachers take too long
As a teacher, we are “forced” to teach from bell-to-bell, so even if I know it’ll only take 20min, I have to stretch it to ~1hr because my bosses think that is better.
@@homeboi808 math is infinite and eternal life is finite and our limited life span is too short at present explain it as fast as possible because I am certain in modern era a lot of people want desire a higher education.
Mo 193 my teacher doesn’t even teach ... LITERALLY... she gives us videos that don’t really help..
I can’t believe I had to go this far to do my dang hw correctly

@Alexia Aflallo Álvarez de Toledo what do u mean?
1➗82=
dragen147 omg same😂
Alexia Aflallo Álvarez de Toledo because we have to solve it by its opposite so if it’s -2 we have to +2 or add 2. and if it’s +2 then we -2 or subtract 2
i'm pretty sure your teacher fully understands what shes teaching, cause it's her job
Does anyone else think that ur getting much more work during online classes than u would during a regular class
Bruh thats exactly my case right now
KPop__is __생명saengmyeong ik i mean they say that because they “want the best from us” when we all know well that they didn’t do so much work back then (im assuming)
Yes and its annoying 😭
Absolutely
KPop__is __생명saengmyeong exactly they expect us to learn new stuff and yet we have no explaining and no help when we dont get it
I wish my math teacher was as good as you
Alexander Dubois same
same here lol
same here
Same my math teacher just gives us paper and says copy whats on the board then gives us a work sheet thinking we know how to do the work and then a week or 2 later gives us a test thing we know how to do the work when she is teaching lessons in 10 to 15 min rushing through stuff cause she likes to talk the entire class time and she cant do stuff visualy she just writes down what in the answer key and does a tiny bit of math in her head and calls herself a good math teacher
The best teachers i want to have is khanacademy and mathantics
Nicely explained. :)
Thumbs up!

Khan Academy is awesome! Being in 7th grade and online school makes learning a burden! Thank you so much!!!!
Bro my math teacher says there is 3 different possible solutions for this
My math teacher just doesn’t explain stuff well he just tells us what to do for 5 minutes and then we have to do it on pencil and paper
This WAS a really good video but iam still very confused 🤷♂️
same
Yeah
I didnt even pay attention im just looking at the comments plus i still dont get it
@@screamingmikewazowski5237 thats probably why

Wow, this video is incredible! My teacher goes crazy fact and usually I can barely keep up. This is going to be a major help throughout the school year.
1. settings
2. speed
3. 1.25
4. Thank me
Thank you 😭
1.5 even
C:D
i expected something funny. how dare u clickbait me
O not doing this because this class is an hour 20 minutes and I want this to go as quickly as possible
As someone who does struggle with adhd and reviewing math before going for a chemist degree, I super duper appreciate you showing us what the equations actually represent. It helps more than you know!
CAN I GET A PRIVATE MATH CLASS?? AND CAN I PLEZ BE ADOPTED??

Not even sure how my teacher is qualified 💀
fr😣
My teacher is overqualified and overwhelms us with an overly complex description of a very simple concept that takes all class
what program does he use to write all the stuff
Ms paint
MrHoolagan I always ask that question! Do you think that program is great for digital art?
Katherine Gonzalez adobe draw is really good for digital art
ms paint is terrible for drawing, use autodesk krita or adobe and or anything else
Probably just MS Paint.
Thank you for these videos and the way u explain things makes it so much easier
Y’all are getting me through my algebra final tomorrow you’re the real MVP
How did you do
Why did you choose to subtract 2n instead of subtracting 5n? This is were i get comfuse because i always choose to subtract or add from the wrong side you need to explain this step. Ive been on you're app and this part gets me stuck
yes i dont understand
Khan is my life saviour, I love these so much especially leading up to final exams.
When my math teacher talks gibberish for a whole class period, I know i can always count on Kahn Academy to make it clear
My teacher could barely teach me this concept for 2 weeks, but this man right here helped me learn it in about 30 minutes! Thanks So Much! :D
Yo- my math teacher took 2 months (it’s still not done) it’s not that _she_ didn’t teach well it’s cuz of that one guy in class who asks nonsensical doubt for attention
they make it so easier for you to understand, really appreciate it🙏
Tell me why whatever my algebra teacher says goes in one ear and out the same ear. (it does a little u-turn) But I actually learn from Khan academy.
Top 10 mysteries that will
Never be solved
Most likely because the videos work at a different pace, and only do one or two problems. In lessons, teachers tend to do several upon several questions, slowly helping you lose focus throughout. Well, that's my own experience and opinion. Maybe it's just because Khan academy is prerecorded, easily accessed, and you can skip time ahead as long as go back.
Excellent as always, clear, made as simple as it needs to be to get to the result, and several ways to represent the problem.
i switched schools and it was an entire year since i had learned how to do this, my teacher literally acts like its the most impossible thing on earth to simply run over this when you did it in 8 minutes. my knowledge is coming back a little so i really have to thank you
I’m still confused only because i have a math question thats looks different from the example question that’s he’s using, but it’s supposed to be the same steps that he uses to solve his...
Thank you so much for the help I am a struggling algebra 1 student taking 9th grade early this help means a lot to me.
all these people talking about how their teacher doesn’t even make sense, for me my teacher doesn’t even do the video herself 😆
Dear Mr. Khan,
I would like to know what program you are using for this. I love the approach you're taking when you write out equations. I've looked through most of your math videos and love the format.
Thanks.
I was struggling to understand how to do equations with polynomials and you helped me a lot!😀
He makes it so simple. Thank you I have a big test coming up in September and this really helped
How did you do?
I'm in Algebra honors, but I never truly understood solving equations with variables (which is a huge part if algebra), until now. None of my teachers have explained it this well or thoroughly, and now I completely understand it. So thank you.
Are you still here
@@GYAOMFEN I actually now teach algebra and am currently taking Differential Equations 2 in college!
@@opaldoesnotrhyme Wow that's amazing!
Super well explained man! I just lurk onto Khan academy for some accelerated learning as the curriculm in my school isn't very vast or dense difficulty wise. Thank you for posting this video!
Just started this and didn't understand it, but this video really helped me what we are looking for in these kinds of problems, and how to solve.
Hah we have a test today and I’m staying sick so this is helping me extra study for the retake 💀
@khan academy you are the best math teacher EVER
You are the best Khan
Honestly there is no one out there on youtube that is as helpful as you
You have helped people getting from an b to maybe an a and this shows improvement which tells us that you are such a great help
Thank you Khan
ho my brother dot whisper
Showing the logic of why you do something in math makes such a huge difference. I don't understand how anyone can learn math in school it was just like now we do this following order of operations without explaining why so as soon as I encountered a problem that wasn't covered in the practice or mixed different concepts I wouldn't be able to figure it out
Me: I want to cryyyyyyy!😭😢
Good teacher 🔥💯
This video was a big help. Thank you so much!
We greatly appreciate you doing this for the world
Awesome.
I find it funny how a 9 minute video teaches me more than my teacher doing 3 periods
An 8 minute video taught me more than 4 classes with my math teacher, thank you :)
wow this literally saved my life he explained step by step thank you
Can i just quit school and just make this my school
Can u be my math teacher
This is a great video on solving equations with variables on both sides.
Thank you so much!!!!!!!!!! I was so confused on my variables and I finally got it!!!!!
I thought I'd be fine with staring at a screen for 8+ hours for school. I was wrong. So so wrong. I can't feel my eyes.
I'm here because of my Algebra class... One word... BYE
Awesome explanation! Thank you so much!!!!
Thank You, Thank you, Oh how I wish I had a teacher like this when I was in high school. In my day, you were not required to take any thing higher than basic math, I have never learned alegebra. I am now returning to school to earn a Bachelors Degree and this site is my new best friend !!!!!! Thank you again, I so appreciate all that you are doing.
You in college now huh?(comment review)
How are u now bro
im a 7th grader taking algebra and ITS NOT IT BRUH. Highkey wanna scream-how the hell did i get into this class anyway i-???
how likely are we gonna math past ninth grade
@@papagurth28 you get math up until 10th grade then its optional
you start algebra in either 6 - 8th grade then move on to algebra 1 (9th grade) then algebra 2 (10th grade) or you can start early like i did which is algebra 1 in 8th grade with algebra 2 in 9th while I took pre-algebra in 6th.
Did you at least have pre algebra?
I don’t get it
This video is so important as you will use these basics forever in numerous other subjects
this is actually practical for a 11-year-old who has been just introduced to algebra...the video's awesome...😊😍😉😄;🤩🙂🎉
My equation is:
2m = 24 + 3m
I'm confused because of the single number on that side do I add?
Just solve for m. There are different ways to approach this equation. The most simple way would be to subtract -3m to the other side so it becomes -m = 24. From here, it becomes m = -24. Another way would be to subtract 2m to the other side with 24 + 3m. Therefore the equation becomes 0 = 24 +m. The last step for this way is to subtract the 24 to the other side, giving you the answer : m = -24. The whole process involves trying to get the variable on one side all by itself.
Was it just me,or did 5:09 blow everyone's mind
it also blew my mind

9 mins to explain how to solve equations with variables on both sides, Mind you my teacher have been trying to get this in my mind for the past 1 week and I have and exam tomorrow.
Such a life saver thank you!
Great explanation, and showing how you can check your own work 👌
sorry, i still dont understand

Thank you sooooooooo much. I'm going into advanced algebra and need this so bad.
Excellently explained, thank you very much
I’m watching a 9 year old video 😂😂
M L Y K A • same 😔🤦🏽♀️
I’m 12 n we r learning this rn😑😑
to much info isn't there a shorter way to do this?
2x+3=5x-2
-2x -2x
3=3x-2
+2 +2
5=3x
Divide by 3 on each side
5/3=x
AKA: x=5/3
takes less than 30 seconds once u get the hang of it
Jocelyn Desantos hi
Yes
Yeah dont and move on with your life.
Its and education video
Thank you so much this cleared everything up for me
This is very helpful thank you for explaining it
I’m gonna fail my test
I don't understand anything.
He explained it really clearly if you dont understand you might want to go to solving equations with one variable
Same 😭😭 My test in Math is tomorrow but i don’t know anything 😪
I understood everything. Thanks a lot 😊
You are a godsend! I finally understand this!!!! Everyone just says subtract this from both sides and add this to both sides without an explanation on why and I'm left thinking huh?????!!!!
You should try to explain slower
You can slow down the video and he repeats things about 50 times...
Just go to settings and change the playback speed
Thank u so much... This helped alot... U were literally my last hope... Im so happy I finally get this
I'm so glad I don't feel stressed anymore haha!
Thank you for the video. It was very educational and helpful with my work
Wow, this helped me A LOT, thank you so much
God bless this man. I have an algebra test tomorrow and probably would’ve failed without this
Thanks this helps a lot I missed a lesson with my math teacher and then I had to watch a video to find out how to do my homework before school it really helps thanks
Thanks this helped me understand how simple this is!!!
This vid seems to be way more complicated than it should be... What I learned was to get all the X variables on one side and all none variables on the other. In other words, subtract the 5X from the right to the left, creating a negative 3X, and subtrating 3 from the left anf moving it to the right. Then you have negative 3X equals negative 5. When you divide the neg. 3 from the X, you get the answer: 5/3.
It's real simple. Just remember to get all variables on one side.
thanks, bro you've helped me a lot
omg thank you so much!!! In my class we’ve been working on this for a week, and I don’t get it, and I have a test on it in two days, so thank you so so so so so much this helped soooooo much
I'm studying for a math test tomorrow and you made me know so much like I have Benin studying my whole life
Thank you so much! Once I learned it, it was a peace of cake! :)
This video helped me so much with my homework thank you !
thank you, you helped alot
Thanks alot Khan academy i was really stumped on this stuff
ur so good at explaining!
khan academy is so helpful. makes it so much easier than how my teachers explain
Thank you so much I have your app and it make learning so easy.
math is one of the subject I strugle with. my teacher does not get that I need to understand it in a differnet way
thank you so much again
My gosh this excactly what i needed because im going to 7th grade but im still in 6th grade in 4th quarter and this really helps ive seen other videos that really help me you should be a online teacher NO joke this would help a lot of kids even kids who are home schooled and have problems with math you would be a great online teacher. Who agrees with me???????? comment yes or no
Wow this actually helped. Thanks!
Wow! Thank You! You're a big help!
Thx a lot I have been unmotivated for a while bc of depression and other related issues
Did rlly helped me have a huge comeback.👍🙌🙌🤙🤙
Wow just amazing, really really good explanation
