Introduction to Algebra
We live in a world of numbers. You see them every day: on clocks, in the stock market, in sports, and all over the news. Algebra is all about figuring out the numbers you don't see. You might know how fast you can throw a ball, but can you use this number to determine how far you can throw it? You might keep track of stock prices, but how can you figure out how much money you've made (or lost) in the market? And you may already know how to tell time, but can you calculate at what times a clock's hour and minute hands are exactly aligned? With algebra, you can answer all of these questions, using the numbers you already know to solve for the unknown. Algebra is an essential tool for all of high school and college-level math, science, and engineering. So if you're starting out in one of these fields and you haven't yet mastered algebra, then this is the course for you!
In this course, you'll be able to choose your own path within each lesson, and you can jump between lessons to quickly review earlier material. AlgebraX covers a standard curriculum in high school Algebra I, and CCSS (common core) alignment is indicated where applicable.

What people are saying
concepts ate built up
Concepts ate built up very well, so you always understand why something is the way it is, rather than memorizing rules.
always understand why something
creators will draw inspiration
I hope other MOOC creators will draw inspiration from this great course.
rather than memorizing rules
bit like groundhog day
Great bridging course from basic maths to algebra:) I liked the videos and loved that you could interact and answer questions within it - the quizzes were designed to ensure you had a proper grasp of the subject matter, one wrong answer and the platform circulates you back around (sometimes a bit like Groundhog Day but at least you are gaining a thorough knowledge of the concept!).
hope other mooc creators
my only complaints
My only complaints is the randomization of the reviews, sometimes they give you really easy problems, but other times they give you harder ones back to back that you have to get correct and you have to watch for any little mistakes you may make.
any little mistakes
every small step
Lots of questions to check your understanding of every small step, and help that is customized to what you find difficult makes it feel like you have your own personal teacher.

but hey
But hey, I guess that's part of the game when you're trying to learn Math.
