# Vectors

Presumably, you've already read the page on the one-dimensionality of ordinary numbers (or scalars), in the Fundamentals section of this site. If not, you may wish to go back and browse that section before you continue reading this page.Introduction

The Cartesian coordinate system

Vectors don't just live on number lines, you know.

Other coordinate systems

There are many ways of writing down vectors.

Vector arithmetic

how to add, subtract and multiply vectors

Vector algebra

Just like scalar
algebra. When you use a pronumeral to stand for a vector, it
doesn't matter what coordinate system you use.
