# What is Algebra?

An easier question to ask might be, "What *isn’t* algebra?" There is algebra in the money we make, save, and spend; there is algebra in the construction of everything from kitchen sinks to automobiles to high-rise office buildings; there is algebra in the preparing, baking, and cooking of food; and there is algebra in watching TV. But only if you’re attempting to figure out the perfect distance you should be from your television set so that your eyes don’t get all buggy.

Algebra is a branch of pure mathematics that deals with the rules of operations and solving equations. Basically, if you’ve got a few pieces of information and are looking for one last bit that will make everything else come together, algebra is there for you. Like *Friends*.

If you think of all of mathematics as a giant wagon wheel with each branch as a separate spoke, algebra would be the hub. It can be directly applied to just about every other type of math you can think of...and probably quite a few that you can’t. To understand any sort of advanced mathematical concept, in other words, you first must wrap your head around the basics: algebra.

Fortunately, the basics are pretty basic. Imagine that.
