Logic
Logic is a formal system of reasoning that deals with the principles of valid inference and correct argumentation, often using symbolic notation to represent propositions and their relationships. It provides a foundation for mathematics, computer science, and philosophy by enabling precise analysis of statements, proofs, and algorithms. In computing, logic underpins areas like Boolean algebra, circuit design, programming constructs, and artificial intelligence.
Developers should learn logic to improve problem-solving skills, write more reliable code, and understand computational fundamentals, as it is essential for designing algorithms, debugging programs, and implementing conditions in programming languages. It is particularly crucial in fields like software verification, database querying (e.g., SQL logic), and AI systems that rely on logical reasoning, such as expert systems or automated theorem provers.
