"The paper 'bear' everything" Are there examples in abstract math that we cannot put plusminus sign before a root? For example, when we calculating the solutions of quadratic equation we use the sign. So, when we don't use it in the Realm of Abstract Algebra?

Any time we don't want to say "plus or minus".

(2) So, there also not hints in Abstract Algebra Realm, so you can see that you can only use only plus or only minus? (I mentioned it cannot be seem in explicit instruction of the question)?
