**Terms **are the **individual building blocks** of expressions. They add up to form expressions. A term is a **product** of its **factors**.

For example, the expression 5*xy* – 3, is made up of two terms, 5*xy* and (-3).

**Factors** are those **variables** or** constants**, whose **product** form a **term** of an expression.

For example, 8, *p* and *q* are the factors of the term 8*pq*.

Factors are such that they cannot be factorised further.

The **numerical factor **of a term is called the **coefficient** of that **term**.

For the terms, 6*y* and 2*xy*, the coefficient of 6*y* is 6 and the coefficient of 2*xy* is 2.
