The authors give a short report made at the end of the national conference dedicated to mathematical education in technological universities. The Conference was held in September, 2010, in Świnoujście, and organized by the College of Mathematics of the West Pomeranian University of Technology, Szczecin. The report gives an overview of the level of knowledge of mathematics by candidates for study at technological universities and methods used in their education. Some conclusions are also drawn.

There are four kinds of scalars in the $n$-dimensional pseudo-Euclidean geometry of index one. In this note, we determine all scalars as concomitants of a system of $m\le n$ linearly independent contravariant vectors of two so far missing types. The problem is resolved by finding the general solution of the functional equation $F(A\underset{1}{\to }u,A\underset{2}{\to }u,\cdots ,A\underset{m}{\to }u)=\varphi \left(A\right)·F(\underset{1}{\to }u,\underset{2}{\to }u,\cdots ,\underset{m}{\to }u)$ using two homomorphisms $\varphi$ from a group $G$ into the group of real numbers ${ℝ}_0=\left(ℝ\setminus \left\}0\right\{,·\right)$.
