Fields of Mathematics

Logic

Logic provides the foundation for mathematical proof and reasoning. Through propositional logic and predicate logic, WIIS systematically explains logical formulas, truth values, quantifiers, and the basic ideas behind proof. These materials provide a starting point for studying university-level mathematics and other theoretical disciplines.

Set Theory

Set theory is the common language of modern mathematics. Focusing on sets, functions, relations, cardinality, and order relations, this course systematically explains the fundamental concepts needed to understand a wide range of mathematical fields. It provides a foundation for further study in areas such as real analysis, linear algebra, and topology.

Probability and Statistics

Probability theory is a mathematical framework for analyzing uncertain phenomena. It provides a systematic study of probability spaces, random variables, discrete and continuous probability distributions, and asymptotic theory, laying the foundation for further study in statistics and machine learning.

Fields of Economics

Microeconomics

Microeconomics is a fundamental field of economics that analyzes the decisions of consumers and firms, how prices are determined in markets, and how resources are allocated. It provides a systematic study of demand and supply, consumer theory, producer theory, market equilibrium, welfare economics, and market failures, helping students understand how market economies function.
