👉 The term "observandum" in the context of mathematics refers to a mathematical object or concept that is defined by its properties. It can be used to describe an abstract mathematical structure, such as a set, function, relation, or ring. In mathematics, an observandum is usually represented by a symbol like a dot (.) or a bracket () around it. This notation allows for the description of the structure in a more compact and concise way than using separate symbols for each component of the structure.
