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.

Good day, I've seen quite a few of your videos (especially the math related one) and find them to be extremely helpful. I'm currently a member of an Old Boys Association for my old high school and would like to give back to my school by creating a Facebook study page where students can share home work questions, as well as find access to key learning material outside of the class room. I would like to know if it's possible to share some of the videos I've videos on that page, just to ensure that students have easy access to your material. Any response would be greatly appreciated! Many

I was using this video as a tutorial when I saw that you solved for no solution. I was confused how you changed 24x on both sides when you started with 28x on the right side of the equation. I solved the problem as x = 23.5
