~~~

Abstract algebra organises organises a wide range of structures into
a logically consistent framework. These classifications can be incredibly useful
for creating composable libraries and APIs.

Examples of types that could be included under the algebraic framework:

- Integers, reals and rationals numbers
- Complex numbers
- Polynomials
- Boolean values
- Matrices and vectors
- Quaternions and octonians
- Strings under concatenation
