I once read, imaginary number is isomorphic to 2d vectors.

Isomorphic as vector spaces, meaning that their additive structure is the same. But the complex numbers are usually not used as a vector space, but rather as an algebraic field, i.e. considering both their additive and multiplicative structure.

Thank you. But I am guessing I need to know a bit of abstract algebra to understand what you are saying which I don't have.
