Lesson 7: Applications

In this lesson you will draw upon the knowledge and skills learnt so far to analyse and write pseudocode for some mathematical algorithms.

Writing Algorithms 1 – Summation

The video below (2:53 mins) provides an overview of steps to design an algorithm and walks through the pseudocode for an example algorithm to sum integers.

Writing Algorithms 2 – Factorial

The video below (1:31 mins) walks through the pseudocode for an example algorithm to calculate the factorial of a number.

Writing Algorithms 3 – Sum of Squares

The video below (1:55 mins) walks through the pseudocode for an example algorithm to sum the first 10 squared numbers.
