Let's make friends with numbers!

The most common "grey" numbers disclose their secrets to the readers step by step. Readers become familiar with the "friendly" numbers, the "perfect" numbers, the triangle- and polygon-numbers, and many more tricky numbers. We recommend this exploration in the number theory to 12-16 years old.
