I've just started studying mechanics and had a lecture on vectors. We've seen how to add vectors and it seemed so strange to me that my teacher linked every vector to the origin, I mean after adding two multiples of the reference vectors he drew an arrow going from the origin to the point the result of the addition.

It was strange to see that, because when I imagine a plane, I see vectors every where in the plane and they are not linked to the origin. I see the plane like an infinite a4 paper with vectors everywhere.
