Intro to Algebraic Expressions & Equations

An algebraic expression is a combination of variables, numbers, and operations (like +, -, *, /). It doesn't have an equals sign.
* Examples of expressions: 3x + 5, 2a - b, y/4

An algebraic equation is a statement that two expressions are equal. It always has an equals sign (=).
* Examples of equations: 3x + 5 = 11, A = L * W, y - 7 = 2

The subject of a formula (or equation) is the variable that's all by itself on one side of the equals sign. It's what the formula is "about."
* In A = L * W, A is the subject.
* In P = 2L + 2W, P is the subject.
