Rearrange formulas to isolate specific variables

Missed the previous lesson?

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.

i swear, with out kahn academy i would be failing algebra

[az]

Thank you so much, I had no clue how to do this in class but now I do!

[hjjassi]

why do we even learn this lol thnx tho

[aliAlyacoub]

so, Basically we isolates whatever we want to figure out

[kanyeeast]

i understand this now for my quiz tmr, but i still dont understand how this is even math

[vfgamer]

If I were to represent using the triangle, would I need to show the 90 degree angle where the base and height intersect?

[Can_be_anyone]

I dont think that people even watch these anymore.But These are very useful

[velvetroze]

another great video khan academy!!! ^ U ^

[redstarline]

when 2 minute video teaches you more than your math teacher did in 3 months 💀💀💀💀

[arevyah]

Why can't I simply divide both sides by 1/2b? So (a)/1/2b=h

[matthewwilson]

we need to build a statue of this man seriously

[speedzz]

With khan academy im failingmath :) XD
