Numeric Expression

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

Expression	Numeric?
$5 + 3 - 2 \cdot 8$	$✓$
$9 w^{2} + 4 s + 7$	$\times$

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.
