Level Entry Level

Many people find numbers and maths to be too complicated especially when it comes to calculations related to the simple activities of their daily life. This course will shed light on the applications of mathematics in real life in general, and particularly when buying and selling. In the course of four weeks, learners will tackle mathematical problems that stem from situations that they encounter daily, at places like restaurants and stores. Learners will be taught how to apply markups and markdowns when selling as well as buying any merchandise.

At the beginning of each week, learners will watch a video of two characters; siblings Omar and Noor. The characters will showcase a problem that requires basic knowledge of the maths of sales and purchase. The instructor draws the connection between these videos and theoretical mathematics using a problem-based approach. Throughout the course, learners will also have access to an array of rich examples that will nourish their understanding of important concepts such as sales, discounts, markups and markdowns.
