Study Notes

Fundamental Concepts

Numbers: Different types of numbers exist, including natural numbers (counting numbers), integers (positive and negative whole numbers), rational numbers (fractions), irrational numbers (cannot be expressed as a fraction), and real numbers (combining rational and irrational numbers). Complex numbers extend the real number system.
Sets: Collections of objects, sets have various operations like union, intersection, and difference. Sets are fundamental to many mathematical disciplines (e.g., analysis, logic).
Logic: Mathematical reasoning using logical statements, deductive reasoning, and symbolic logic. This is crucial for building and proving mathematical arguments.
Functions: Relationships between inputs and outputs, where each input corresponds to one output. Functions are fundamental in modeling relationships in different areas.
