Numeric Expression

Numeric, or numerical, expressions only contain operations involving numbers. Consider these example expressions.

Expression	Numeric?
$5+3-2\cdot8$	${\color{#009600}{\huge{\checkmark}}}$
$9w^2+4s+7$	${\color{#FF0000}{\huge{\times}}}$

The first example above is a numeric expression because it only contains numbers and operations between them. The other expression, however, contains variables. Therefore, it cannot be a numeric expression, but instead is an algebraic expression.
