1. Types of Algebraic Expressions

 Monomial-Which has only one non-zero term.
 Binomial-Which has two non-zero terms.
 Polynomial- Which has more than one non-zero terms with non-negative integral exponents.

Monomial

A monomial is an algebraic expression that has only one non zero term. Examples of a
monomial expression:

 a is a monomial in one variable a

2
 10ab is a monomial in two variables a and b.
2
 5m n is a monomial in two variables m and n.

 -7pq is a monomial in two variables p and q.
3
 5b c is a monomial in two variables b and c.
 2b is a monomial in one variable b.

 2ax/3y is a monomial in three variables a, x and y.
