# Rings and Fields in SageMath

Due to my initial formation, I have some difficulties with the numerous rings or fields used in Sagemath. I do not find a clear explanation and enumeration. Of course my problem is not with the standard rings (`ZZ`

, `RR`

, `CC`

...) but all the other like `QQbar`

(field of algebraic numbers), `AA`

(the field of algebraic reals)...

My question is not a mathematical question but is correlated to SageMath
