What Is Algebra? (The Foundation of All Math)
Algebra is about solving for unknowns. You're given a situation a relationship between values and your job is to figure out what the missing piece is. It's the math of "if I know these things, what can I figure out?"
Most students encounter algebra in middle school and work through it across several levels. Pre-algebra gets you comfortable with variables and basic operations. Algebra I introduces equations, inequalities, and the idea that letters can represent numbers. Algebra II goes deeper with functions, polynomials, and logarithms. Then there's linear algebra, a college-level course that's a different beast entirely (more on that in the FAQ).
A real-world example: say you want to pay off a $3,000 credit card at $150 per month. Algebra lets you calculate exactly how long that'll take. You're solving for a variable the unknown using a relationship you already know.
Algebra is the language of math once you speak it, everything else gets easier.
