20 18 national college entrance examination mathematics volume one answer
First of all, the college entrance examination questions also allow candidates to have different answers, which is normal. In most cases, look at the result first, and then look at the problem-solving process. Generally, if the result is correct, the process is organized and the students' judgment is correct. However, there are only a few final questions in the college entrance examination mathematics, and the basic thing that can be done is that the mathematics strength is relatively strong and the influence on the results is weak. Coupled with the error of manual marking, it shows that the teacher's worry is redundant, and the college entrance examination cannot be divided for individual students to solve problems.
