Definition

• This group is the set of real algebraic numbers under addition.
• This group is the additive group of the field of real algebraic numbers.

This group is often denoted $(\mathbb {A} ,+)$ or simply as $\mathbb {A}$.

Group properties

Property	Satisfied	Explanation
Abelian group	Yes	Addition of real numbers is commutative
Nilpotent group	Yes	Abelian implies nilpotent
Simple group	No	Any non-trivial proper subgroup is a normal subgroup since abelian. It has such subgroups, for example additive group of rational numbers.
