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
