How many minutes do primary school students think about mathematics?
Math problems in primary schools are not difficult, they are all basic problems. Generally, it takes only 20 seconds to understand this problem in class, so it is normal for a primary school student to do a problem for one minute, but if he has just learned something new, it may take three minutes. So it depends on students' proficiency in knowledge; But if a student doesn't listen to the book in class, he won't understand it for long.
