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.

With Fractions, couldn't you just find the common denominator and just cancel them out? For example, you have 3/4 + 2/8. Couldn't you just change 3/4 to 6/8 and be left with 6 + 2?????

4 years later, the answer is I don't know, why? because I'm a 7th grader that needs to upgrade his math second I think no because there is a specific way to do each math in the world, not just randomly add them or divide nor multiply or subtract.

And God will do something amazing in your life. Unexplainable peace will come into your life. The Word of God promises you peace which surpasseth all understanding.
