Algebraic expressions | Algebra basics | Math | Khan Academy
The core idea in algebra is using letters to represent relationships between numbers without specifying what those numbers are! Let's explore the basics of communicating in algebraic expressions.
Solving equations & inequalities | Algebra 1 | Math | Khan Academy
There are lots of strategies we can use to solve equations. Let's explore some different ways to solve equations and inequalities. We'll also see what it takes for an equation to have no solution, or infinite solutions. **Unit guides are here!**
