Here's why:

* Social Sciences: These fields focus on the study of human societies and the relationships between individuals within those societies. They use methods of empirical investigation and critical analysis to understand social phenomena. Examples include sociology, anthropology, psychology, economics, and political science.

* Mathematics: This is a formal system of knowledge that deals with quantities, structures, space, and change. It relies on logic, abstraction, and rigorous proof.

While mathematics can be used as a tool in social sciences to analyze data and model social phenomena, it is a distinct discipline with its own fundamental principles and methods.

Key Differences:

* Subject Matter: Social sciences study human behavior and societies, while mathematics deals with abstract concepts and relationships.

* Methodology: Social sciences rely on empirical observation and interpretation, while mathematics emphasizes logical deduction and proof.

* Focus: Social sciences aim to understand human behavior and social structures, while mathematics seeks to explore and understand abstract relationships and patterns.

Therefore, although there are connections and applications of mathematics in social sciences, mathematics itself is not considered a social science.
