This article looks at knight's moves on a chess board and introduces you to the idea of vectors and vector addition.
A short introduction to complex numbers written primarily for students aged 14 to 19.
The article provides a summary of the elementary ideas about vectors usually met in school mathematics, describes what vectors are and how to add, subtract and multiply them by scalars and indicates why they are useful.
This problem encourages students to think about vectors as representing a movement from one point to another. The need for coordinate representation of points will emerge automatically and the problem naturally requires an interplay between geometry and algebra.
Polygon Walk explores vector walks which form polygons around the origin.
