Refers to the object and method of mathematics, which is more complicated than elementary mathematics.

In a broad sense, all mathematics except elementary mathematics are advanced mathematics, and some call algebra, geometry, simple set theory and logic in middle school intermediate mathematics, which is the transition between elementary mathematics in primary and secondary schools and advanced mathematics in universities.

Generally speaking, advanced mathematics is a basic subject formed by calculus, algebra, geometry and their intersection.

The main contents include: limit, calculus, spatial analytic geometry and linear algebra, series, ordinary differential equations.
