Robinson Arithmetic

Robinson Arithmetic, developed by mathematician John Robinson, is a simple and formal system for arithmetic, focusing on natural numbers. It uses a limited set of axioms and rules to define operations like addition and multiplication without relying on complex structures or concepts. Robinson's approach emphasizes foundational principles in mathematics, showing that even basic arithmetic can be constructed from very few assumptions. This system serves as a valuable tool for understanding the basics of mathematical logic and the foundations of number theory, illustrating how complex mathematical ideas can emerge from simple starting points.
