In computer science, a value is an expression which cannot be evaluated any further (a normal form).

The members of a type are the values of that type.

For example, the expression 1 + 2 is not a value as it can be reduced to the expression 3.

This expression cannot be reduced any further (and is a member of the type Nat) and therefore is a value.
