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

Expression	Numeric?
5+3−2⋅8	$✓$
9w2+4s+7	$\times$

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