There are four kinds of scalars in the -dimensional pseudo-Euclidean geometry of index one. In this note, we determine all scalars as concomitants of a system of linearly independent contravariant vectors of two so far missing types. The problem is resolved by finding the general solution of the functional equation using two homomorphisms from a group into the group of real numbers .
