comment Quotient ring of a polynomial ideal with two variables
Thanks for the great answer! If I understand you correctly I assume all the equivalence classes are of the form $[a \cdot 1], [a \cdot y], [a \cdot y^2]$ with $a \in \mathbb{C}$. Thus, $\operatorname{dim}_{\mathbb{C}}\mathbb{C}[x,y]/I = 3$?

comment Solving polynomials in $\mathbb{Q}[X]$ exactly
There algorithms for addition, multiplication and inverses of interval representations. Unfortunately, they have polynomial complexity which can be slow for this basic operations. See chapter 8 of Mishra's "Algorithmic Algebra" about real algebraic numbers.

comment Number of elements of order $7$ in a group of order $28$
If I assume $G = \mathbb{Z}_{28}$ is $<7> = \{0,7,14,21,-7,-14,-21\}$ ?
