Arithmetic as `pure' and `applied'
One often hears mathematics classified into two categories: pure or applied, abstract or concrete, elementary or modern. We will explore how arithmetic can dismantle such highly artificial distinctions. More specifically, we will play with tiles and draw pictures to highlight how arithmetic can be good mental exercise and a very useful tool for modern communication.
