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.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

got a score 44/50 on my quiz because of this! Thanks Sal!

[FernandoFloresLopez]

Oh my gosh thank you! My algebra 1 teacher talks too fast, and this method is even more easy than she taught me!

[sarahpaulson]

Wow, So you just combine like terms! 😐

[ethanbolen]

Thank you so much! 
I have been struggling in school because I couldn't understand what I had to do but after I had watched this video it all made sense!

[PimpMatt]

Thanks for refreshing my mind. I came to class late and had no idea what the teacher was lecturing about. She talks pretty fast. Simple stuff.

"This something" and "that something" helped me so much lolz

[molten_bread]

I was totally overthinking how to do this. Still a life saver over a decade later

[mikafigueroa]

Thank you so much, Its really help in my assignment! 

[saudalkaabi]

Now I know why my math teachers have been like “ if you don’t understand, do the Khan academy assignment “ jeez, I was freaking out cuz I’ve got a test today and I forgot how to add polynomials, Sal fixed that in 2 minutes.

[theonetheonlychickenpermis]

thanks. I needed to refresh my skills. also do you notice there's so many views but so few comments?

[Sei]

I had a student who asked if I could help him. I don't teach math and even though I teach programming, I don't really do polynomials in this way anymore so it's good to know that it's still in there.

I am from the US but I live in the philippines and don't speak bisaya. My teacher likes to start speaking bisaya when she is supposed to teach in English and I can never undestand. Tysm for this

[ploppy]

Thank you!! This really helped me a lot because I was absent from school the day we learned this.

[gfetboi]

My teacher made me keep the parentheses and do this super complex version. Thanks for this, you probably saved me for tomorrow’s test.

[rangerocket]

You can also do this in stacked format by combining like terms in parentheses

[justyourcoolgrandpa]

tnx khan academy u helped me so much in my homeworks

[yahyamalik]

Thank you so much. I have a test tomorrow and my math teachers is so bad at explaining this video saved me from failing my exam😅

[mijumaru]

thanks, it really helps my final exam! and it is easy to understand

[OliviaBowers-mrel]

Wow this helped me and made me understand so much thank you so much
