👉 In mathematical logic, a unary operation is called "ungroupable" if it can be expressed as a single binary operator (i.e., a function) on any set of variables. This means that an ungroupable unary operation cannot be decomposed into two or more simpler operations. For example, the operation of taking the square root of a number is not groupable because it only has one input and only one output. In other words, a unary operation is called ungroupable if it
