Event description

We are all very used to reading, understanding and calculating using numbers in a normal decimal system – using hundreds, tens and units. But there are other ways to represent numbers, which are not quite so familiar. From the ancient Mayan vigesimal system, through to modern computer binary and hexadecimal –Katie Steckles will help students explore these other ways to write numbers, and discover some puzzles and games we can play with them.

About the speaker

Katie Steckles is a mathematician based in Manchester who gives talks and workshops on different areas of mathematics. She finished her PhD in 2011, and since then has talked about mathematics in schools, at science festivals, at music festivals, as part of theatre shows and on the internet. She enjoys doing puzzles, solving the Rubik's cube and baking things shaped like mathematics.

Please note

This workshop is strictly for 16–18 year–olds and will include a 45 minute unsupervised lunch break. Students should bring lunch and a drink, pens, pencils and a calculator. 

The Mathematics Summer School workshops are based on Ri Mathematics Masterclasses. Students who have attended a Masterclass series which included a session on a similar topic may have already seen some of the content in this workshop. Please contact us on with any questions.
