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.

[alexdubois]

I wish my math teacher was as good as you

[screamingmikewazowski]

Khan Academy is awesome! Being in 7th grade and online school makes learning a burden! Thank you so much!!!!

[Jacob-mxie]

CAN I GET A PRIVATE MATH CLASS?? AND CAN I PLEZ BE ADOPTED??

[razn.r]

This WAS a really good video but iam still very confused 🤷‍♂️

[cee]

Not even sure how my teacher is qualified 💀

[freshappleseed]

Wow, this video is incredible! My teacher goes crazy fact and usually I can barely keep up. This is going to be a major help throughout the school year.

As someone who does struggle with adhd and reviewing math before going for a chemist degree, I super duper appreciate you showing us what the equations actually represent. It helps more than you know!

[milady]

all these people talking about how their teacher doesn’t even make sense, for me my teacher doesn’t even do the video herself 😆

[janellafrancis]

Khan is my life saviour, I love these so much especially leading up to final exams.

Why did you choose to subtract 2n instead of subtracting 5n? This is were i get comfuse because i always choose to subtract or add from the wrong side you need to explain this step. Ive been on you're app and this part gets me stuck

[shulaarmintor]

Tell me why whatever my algebra teacher says goes in one ear and out the same ear. (it does a little u-turn) But I actually learn from Khan academy.
