We quickly review mathematical induction and then solve a few related problems of various levels of difficulty, from easy to very hard.

Handouts: Handout

Today we will approach problems involving area computations, that should hopefully cover all necessary techniques for Olympiad problems.

Handouts: Handout

Today we will discuss various standard techniques in solving diophantine equations (i.e. equations with integers). The material is for 2 weeks.

Handouts: Handout

The handout is the same as last time (see Part I)

We will move on to problems 4, 5, 6... and so on today.


Today we are doing problems involving mathematical games, and talk about the method of retrograde analysis.

Handouts: Handout

This lecture we continue with the same topic. We added a few extra problems

Handouts: Handout

Today we will do practice problems, with no particular theme.

Handouts: Handout

Today we discuss angle chasing, properties of angles inscribed in circles, and a few constructions.

Handouts: Handout

We continue with the topic from last time.


Today we will discuss board problems, involving colorings, tilings and more.
