Abstract

The article offers interested readers complete solutions to six themed problems from secondary-school mathematics. We have focused on problems from the field of number theory that have appeared in the international competition Mathematical Kangaroo. In the final part of the article, a more general solution to the problem of finding the last non-zero digit of the number is presented, along with a useful formula for its quick determination.
