What are vertibles and invertibles?

Answer 1

In mathematics, a "vertible" is not a recognized term. However, an "invertible" element refers to an element in a set that has an inverse with respect to a specific operation. For example, in the context of matrices, an invertible matrix is one that has a multiplicative inverse, allowing it to be multiplied by another matrix to yield the identity matrix. Invertible elements play a crucial role in various mathematical structures, such as groups, rings, and fields.
