# polynomial

In math, a polynomial is a mathematical expression that contains two or more algebraic terms that are added, subtracted, or multiplied (no division allowed!). Polynomial expressions include at least one variable and typically include constants and positive exponents at well. The expression x2 − 4x + 7 is a polynomial.

You can break the word polynomial into parts to understand it more clearly. Poly means "many" in Greek, and nomial comes from the Latin nomen, or "name." In a mathematical context, this becomes "many terms." There are a few other rules about polynomials (exponents must be positive integers, for example), and your math teacher can fill you in on them.
