How can I count from the bottom of the class to a positive number?

Listen carefully in class, actively ask the teacher's questions, complete the teacher's homework carefully after class, and unite and love each other.

This is a math problem, how can the upstairs be answered according to pedagogy.

When there's only one person in the class, it's fine.

The students who are the first in the annual exams in our class don't even go to the class reunion, the reason is...

When I was in school, the teacher would always favor those who had the best grades in the class, and the poor students in the class became a thorn in the side and a thorn in the flesh of the teachers. Poor students will be scolded and punished for no reason if they do not do well in the exam, and the teacher will encourage the excellent students if they do not do well in the exam. After many years, the students are now in **?

At every class reunion, the first and last places of the year are always the topic of small talk, let's see what their situation is now!

<> fact, the quality of learning does not accurately determine a person's future, although God arranges you to appear in different situations, but there is always a path that suits you, go the right way, you will succeed. If you go wrong, you can only sigh alone. Some people are born to be kings, so they don't go with the world, they always move in the direction they yearn for, even if they are alone along the way, they will never give up.

And some people are born as tools for reading, and they will only bury their heads in hard study, and there seems to be nothing meaningful except for learning. Don't look down on anyone at will, maybe the next second he will be the next Jack Ma! In the final analysis, the reason why successful people are successful is because they "have unique skills", 360 lines, and they are the champions in every line.
