It is often used when working with complex algebraic structures like groups, rings, fields, etc., which require the ability to reason about their properties and structure. Formisms can be thought of as a kind of abstract language that allows mathematicians to express mathematical concepts in an explicit and precise manner without needing to rely on concrete examples or
