I   often get asked about the purposes of doing mathematics. Why do mathematics when it is so difficult, so inaccessible and so unfriendly and uncool? Why do so many students hate and fail mathematics? Why do so many people feel comfortable with the fact that they cannot do mathematics or they were never good at mathematics? It is a well-known fact that Mathematics has a widespread public image as being difficult, cold, abstract, theoretical, ultra-rational but important.
