Although Mr. Wei writes like a book on the blackboard, his classes are always packed. Some students even sit in the aisle and put their schoolbags on the ground as desks, which shows their enthusiasm. In fact, however, it is not easy to attend teacher Wei's class. Sometimes the teacher has finished the problem before the students can react. Even some students haven't understood the topic, so they can only ask the teacher to repeat it. Students' love for Mr. Wei is not limited to the classroom. After class, students will take the initiative to ask Mr. Wei for answers if they don't understand anything, and the teacher will answer them seriously, and they don't care about "sacrificing their rest time."
How can the dedicated teacher Wei not let the students love more and more? There are specialties in the technical field, and each subject has its own specific expression symbols, and mathematics is naturally one of them. Every time I see the gobbledygook on the blackboard, my classmates can't help but be glad that they passed CET-4 and CET-6 successfully. Otherwise, don't say you don't understand, just copying notes may be wrong.
