Usually, if field "C" can be calculated from fields "A" and "B", I wouldn't save field "C" separately.
OTOH, a default value is only the initial value. Triggers would give you an error message, related to "recursion".
I am not sure whether validation rules (at the record or field level) can solve this, but I would just place the update commands on the form where the user accesses the table (TextBox.InteractiveChange()).
