What does numerical coefficient mean? In general, a numerical coefficient is a number.

What does numerical coefficient mean?

A numerical coefficient is the number that comes before the variables in a mathematical expression.

Here are some examples of the coefficients.

Example 1.

5x

The numerical coefficient is 5.

Example 2.

10xy

The numerical coefficient is 10.

Example 3.

34x^{3}y^{2}

The numerical coefficient is 34.

Example 4.

(15x^{3}y^{2})/27

The numerical coefficient is 15/27. Why?

(15x^{3}y^{2})/27 =

(15/27)x^{3}y^{2}

(15/27)x

The (15/27) is the number that comes before the variables.

As you see, the numerical coefficient can be a fraction.
