The importance of mathematical symbols in mathematical research is self-evident. Mathematical symbols are one of the important learning elements in mathematics. Scientific and rational use of mathematical symbols can promote people's understanding of abstract knowledge, improve calculation efficiency, help people solve more complicated and difficult mathematical problems to a great extent, and play an important role in mathematics learning.

At the same time, mathematical symbols are also an important part of mathematical language and one of the most basic means to express mathematical concepts and ideas. In mathematical research, the use of symbols can help us better understand and describe problems, so as to better solve problems.
