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.
For free. For everyone. Forever. #YouCanLearnAnything
