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. Practice this lesson yourself on right now:Īlgebra I on Khan Academy: Algebra is the language through which we describe patterns. Sal find the formula of a function that, given an input value 'b,' outputs a value 'a' that satisfies the equation 4a+7b=-52.
