Getting a feel for equations and inequalities
The core underlying concepts in algebra are variables, expressions, equations and inequalities. You will see them throughout your math life (and even life after school).
This tutorial won't give you all the tools that you'll later learn to analyze and interpret these ideas, but it'll get you started thinking about them.
This video will give you a great understanding of variables, expressions, and equations. If you've struggled with them before, this one may just do the trick!
Here we have a problem that asks us to identify which variables are dependent and independent. Hint: independent variables are not influenced and remain unchanged by the other variable.
It's helpful to express an equation on a graph where we plot at least 2 points. Watch and we'll show you.
We're flipping the last video on its head and doing the opposite. This time we give you the graph and ask you to express it as an equation.
