Question

The inverse of each element in R is​

Answer 1

• If every other element has a multiplicative inverse, then R R R is called a division ring, and if R R R is also commutative, then it is called a field. In general, the set of elements of R R R with two-sided multiplicative inverses is called R ∗ , R^*, R∗, the group of units of R . R.
