First of all, the lethality of mathematics means that wrong assumptions or wrong ways of thinking may lead to mistakes in the field of mathematics. A common example is that an inappropriate mathematical formula is applied to a specific situation, resulting in a wrong result. This is an inevitable mistake in mathematics learning, but only through constant practice and correction can we master the correct methods and skills.

Secondly, the fatal of mathematics may also be the defects and limitations of mathematics. For example, it can't cover all possibilities and needs the support of other scientific fields, such as statistics and computer science. In addition, mathematics may fall into wrong assumptions or a lot of useless reasoning, which leads researchers to follow the requirements of scientific methodology, conduct experiments and investigations, and ensure the relevance and practicability of their own mathematical problems.

Mathematics is fatal because its unique thinking ability has not been popularized enough. Although mathematics has been widely established as an important basic subject, many people are still afraid and challenged when facing mathematical problems. This may be caused by poor education or poor teaching methods, and to solve this problem, more educators and scientists need to devote themselves to popularizing mathematical ideas and techniques and show the importance of mathematics in various fields.
