Addition

Definition

Addition is a fundamental mathematical operation that combines two or more numbers to yield a total sum. It serves as a basic building block in arithmetic and plays a vital role in more complex mathematical concepts. In the context of formal systems, addition is crucial for representing numbers and performing calculations, linking it to concepts such as Gödel numbering and the framework of primitive recursive functions.
