👉 "Indecomposability" is a concept in mathematics and computer science that refers to properties of objects or structures that are invariant under any operation, including addition. This means that if you add two elements together, their sum will always be the same regardless of which element is added first. For example, consider the set of all integers (Z) with the operation +, where + means addition. If we define a new operation - on this set, it would mean subtracting one element from another
