It is difficult to summarize the difficulty of mathematics in the national examination paper. Because the mathematics level of different candidates is different, the difficulty of the topic will be different. However, from the authoritative interpretation and the reflection of the majority of candidates, we can understand the difficulty of mathematics in the national examination paper to some extent.

First of all, from the perspective of authoritative interpretation, mathematics teachers in education departments and majors usually interpret and evaluate the mathematics test papers in the national volume in order to provide guidance and reference for the majority of candidates. According to the results of these authoritative interpretations, the difficulty of national paper mathematics usually varies according to different years and levels.

However, in most cases, the difficulty of national paper mathematics is considered to be relatively high. This is because the design of national mathematics test papers often involves high mathematical theoretical knowledge and complex calculation methods, which requires candidates to have strong foundation and calculation ability.

Secondly, from the reflection of the majority of candidates, it is generally believed that the mathematical difficulty of the national paper is higher than that of the provincial paper. This is because the national volume is usually designed by many experts, and the design is relatively difficult. Moreover, the mathematics test questions in national papers are often more comprehensive than those in provincial papers, which requires candidates to have higher comprehensive application ability.

However, it should be noted that the difficulty of mathematics in the national paper does not mean that all candidates will encounter difficulties. Because the purpose of the exam is to measure a person's level in a certain field.

Therefore, the difficulty design of the national mathematics test paper should take into account the ability level of most candidates in this category. If it is too difficult or too simple, there may be something wrong with the design of the test paper.

To sum up, the difficulty of national paper mathematics is not a simple problem. Its difficulty usually varies according to different years and levels.

However, in most cases, the difficulty of national paper mathematics is considered to be relatively high. However, we also need to realize that the difficulty design of the test paper should take into account the ability level of most candidates, rather than targeting a few people or being too popular.
