We evaluate for real numbers: 1. In first-order logic the existence of an additive inverse; and 2. In second-order logic the least-upper-bound property, stating every bounded, nonempty set of real numbers has a supremum. Both are not tautologous. This confirms modal propositional and predicate logic. The negative results form a non tautologous fragment of the universal logic VŁ4.
