Course Objectives & Outcomes

Z
Creative problem solving, with fun tricks and geometrical illustrations of the results.
Z
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).
Z
How to derive some less known formulas, using cool computational tricks.
Z
You will learn (from an article) how to convert infinite periodic decimal expansions into fractions, by smart substitutions and solving linear equations.
Z
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!
Z
How to derive the formula for the sum of squares of all natural numbers from 1 to n.
Z
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.
Z
How to prove divisibility in some simple cases, using very basic (but fun) reasoning.
Z
You will learn (from an article) some basics about continued fractions (CF), and how to recognise irrational surds from their infinite periodic CF-expansions.

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.

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.
