Right handed coordinante

the following sentence is not clear. "The determinant of a set of vectors is positive if the vectors form a right-handed coordinate system, and negative if left-handed." what does "right-handed coordinate system" means? the "coordinate system" article does not mention it. amit man

Determinant inequalities

There is a problem with the determinant inequalities in the properties with determinants section. If we take the determinant of a commutator

then

But if and has a non-zero determinant, there is a contradiction. — Preceding unsigned comment added by Username6330 (talkcontribs) 21:56, 10 November 2017 (UTC)
