Difficult! Compared with previous years, the national mathematics test questions in 20 17 are obviously more difficult. Interested friends can have a look at last year's national mathematics examination paper (20 16). Compared with this year, for example, last year's college entrance examination, statistics combined with previous figures and shapes, this year is entirely Chinese characters, it is difficult to understand the meaning of the question. Are there many candidates who were plural last year, and this year they don't choose plural at all?
