As is the usual tradition we’ll start with some properties of 14, first words to WolframAlpha which provides properties for any number entered including the prime factorisation and various properties. If we choose to investigate fourteen as word instead we could look for example at the frequency of use over time as well as definitions of the word.
A great site for investigating number properties is Tanya Khovanova’s Number Gossip site, here we learn that 14 is a Catalan number, composite, deficient, even, odious and square free. The site gives clear definitions of all the terms used.
Thinking about older students including those going into higher education Colleen Young (that’s me!) wrote this post ‘For Students‘.

This is a carnival so we should really end with some music – mathematical songs of course!
