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.

How do they almost have 10 million subscribers

Or you could (once again) just do 9 divided by 3. Explanations like this are honestly relatively hard for me to grasp when there's a much easier and more obvious way to solve the problem (9 divided by 3). I wish Sal had used some different numbers because I don't feel like I learned what he was trying to teach.

Damn thanks so much, I knew how to do it but I never knew how to visualize it, especially the fraction part (had no intuition to why 1/3 was representing)... Thanks for the video

You can just divide 9 boxes by the x-boxes
