logic and set theory
Logic is the systematic study of reasoning and the principles of valid arguments. It provides a framework for evaluating the correctness of statements and determining the truth or falsehood of propositions. Set theory is a branch of mathematics that deals with the study of sets, which are collections of objects or elements. It explores the relationships between sets, including operations such as union, intersection, and complement. Set theory provides a foundation for other branches of mathematics and is used to define and analyze mathematical structures.
