Both of them are advanced mathematics, but in contrast, A 1 is wider than B 1 and contains more comprehensive knowledge.

2, the difficulty of knowledge is different:

On the same knowledge point of A 1 and B 1, the depth and difficulty of explanation are different, A 1 has a higher level, and A 1 has higher requirements for the same knowledge point.

3, the applicable population is different:

A 1 is generally used in a professional field with higher requirements for mathematics, depending on the depth and breadth of application fields, while B 1 is suitable for people with lower requirements and does not need to master so much mathematical knowledge.

Extended data:

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: series, limit, calculus, spatial analytic geometry and linear algebra, series, ordinary differential equations.

Basic subjects for postgraduate examinations in engineering, science and engineering and finance.
