Course Objectives & Outcomes
Creative problem solving, with fun tricks and geometrical illustrations of the results.
How to derive the formulas for partial sums for two very important examples of arithmetic progressions: 1+2+…+n and 1+3+5+…+(2n-1).
How to derive some less known formulas, using cool computational tricks.
You will learn (from an article) how to convert infinite periodic decimal expansions into fractions, by smart substitutions and solving linear equations.
You will learn (from an article) about an interesting family of nested square roots and how to prove that some members of this family are… integers!
How to derive the formula for the sum of squares of all natural numbers from 1 to n.
How to derive the general formula for partial sums of geometric progressions; an important example of the sum of all the natural powers (from 1 to n) of 1/2.
How to prove divisibility in some simple cases, using very basic (but fun) reasoning.
You will learn (from an article) some basics about continued fractions (CF), and how to recognise irrational surds from their infinite periodic CF-expansions.

Great course, don't hesitate to buy Hania Uscka-Wehlou courses... is a great instructor/teacher!

This is a breath of fresh air; ways of thinking about numbers and their relations that I have not come across, and will broaden my maths vision.

I love Professor Hania's classes. She generously offers 3 free courses and in a Bonus Lecture for the free courses she is providing coupon codes that give big discounts for her paid courses (as of 10-6-25). I learned a lot in this class and I appreciate Hania's slow, step-by-step, clear, patient approach. I feel like she wants me to know math! Thank you, Hania! (I'm slowly working through the Discrete Math 1 course and enjoying it : )

Courses like maths should be designed for slow learners like me and I guess this is how I want to be taught mathematics, all the explanations to be precise and slow-spoken.

Everything was clearly explained, but Im just curios about the thinking skill on the frist step derivation,step of the starting derivation, the mathematics is already know but the ideas to derive is not there yet.
Overall,Thank you, I really enjoyed the whole courses

It was very interesting. The solutions were all tractable.
The only thing I was missing is some comment on how to come up with the approaches in the derivation part.
Do you have to be able to see it or is there a more systematic way?

The way you teach is so important because you demonstrate the principles and thought process. Some people teach math just by going through the steps to a solution, but what is often missed is the art of the demonstration. I truly appreciate how you guide us to the discovery which is quite difficult to do without mechanically drawing out the conclusion. Sometimes I find that I will pause your video and I might think for an hour or even I stop the lesson. It might be that I need to really think about what you just did. Or I don't quite understand so I don't want to just overlook it. So I may do something else. At some time later it will come to me. I think about something that you said maybe even a month ago from the time I last studied your lesson and I find some pearl. Just amazing!!! That is when you know that you are truly a superb instructor. I hope you will continue to teach us because there is no one quite like you.

Very nice selection of interesting maths problems! Highly recommended for everybody who likes mathematics, even for high-school students. Interesting articles with stuff (like continued fractions) that was completely new to me. This is my 11th course by Hania and Martin that I've completed and I can recommend all of them.
