Copying homework is also a science. If you copy the students' homework well, if you can copy more than three copies and have time, if their answers are all the same, you can think about why they write like this. If the answers are inconsistent, you can calculate one side (not a big number) according to the formula listed by them. Anyway, the sixth grade math only needs to recite one formula. I'm in grade six, too. That's how I copied it. I didn't go to class The exams are among the top in my class. )
