We introduce translations in the rational plane. However we do not assume the conventional understanding of functions and mappings, which actually has some logical difficulties and conceptual disadvantages. We prefer a cleaner and more flexible understanding emphasizing the use of expressions.

This video belongs to Wildberger's MathFoundations series, which sets out a coherent and logical framework for modern mathematics.

  • The notation "point first", mean that we are the point and we pass throw the fonction to go to another place.

    The classical way is passive in the sense the point is "acted".

    And like this, it's more easy to considere the fonction like a independant object.
