Inženjersko tehnički priručnik 1 – Matematika – mehanika
The first book in the series covers topics in mathematics and mechanics. These include basic mathematical concepts, differential and integral calculus, vector analysis, kinematics and dynamics.
The textbook Arithmetic by Dr. Franjo Hočevar, which served as the basic teaching material for upper secondary school grades in the first half of the 20th century, includes key arithmetic concepts adapted to the educational curriculum of the time.
This booklet should not be understood as a serious introduction to number theory, but rather as a reading intended for students in upper elementary school and lower secondary school, i.e., ages 13 to 17.
