**Polynomial** comes from *poly-* (meaning “many”) and *-nominal* (in this case meaning “term”) … so it says “many terms”. They contain-

constants (like 3, −20, or ½) |

variables (like and x)y |

exponents (like the 2 in y^{2}), but only 0, 1, 2, 3, … etc are allowed |

Monomial, Binomial are some other names expressions containing one, two and three terms respectively.

- If you add polynomials you get a polynomial
- If you multiply polynomials you get a polynomial

So, you can do lots of additions and multiplications, and still have a polynomial as the result.
