- complex numbers, i.e. with complex number multiplication
- with the cross product
- quaternions, i.e. with the quaternion multiplication
An algebra over a field where division exists.
Notably, the octonions are not associative.

A vector field is a mathematical construct that assigns a vector to every point in a space. It can be thought of as a way to represent spatial variations in a quantity that has both magnitude and direction. Vector fields are widely used in physics and engineering to model phenomena such as fluid flow, electromagnetic fields, and gravitational fields, among others.
