This can be hard for students to cope with because passing Algebra II is necessary in order to attend most colleges and it usually opens the gate to harder math classes that could be taken in the future, like calculus. Forever.Many students who have never had any struggle handling math concepts in their past math classes begin to feel like they have hit a metaphorical wall when they start Algebra II and there is no way around it. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.įor free. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We tackle math, science, computer programming, history, art history, economics, and more. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.Ībout 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. In these tutorials, we'll cover a lot of ground. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design.

Without it, it's impossible to move forward. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. It's also seen as a 'gatekeeper' subject.

As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. Sal introduces the concept of 'domain' of a function and gives various examples for functions and their domains.Īlgebra I on Khan Academy: Algebra is the language through which we describe patterns.
