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.

My problem is much more complicated than that and I have to find the second equation. It doesn’t even mention it. I can solve it in my head with ease but putting it through a useless equation that just waste time is a headache.

So I'm in Algebra Honors and taking algebra in middle school instead of highschool. I find this lesson to be extremely simple but I can't fail my quiz today (not the best at math nor test taking)... Thanks for the word problem I was able to practice with

Oh my god, I just switched schools, and I tested into algebra 1, 2 levels above my grade level, and I have been using khan my whole life and they don't use it and it is super confusing. I spent so long trying to figure out how to set up the equations and within the first minute of the video my problem is solved, tysm

the fact that we're only learning this now and that I could've learned it years ago if I wanted to...

I’m about to take a test on this tomorrow and I thought it was so hard but it’s actually so simple! I’m in accelerated math and my teacher recommended me for honors, but I can go into geography if I bring my grade up this half of the year. Wish me luck!
