Total price/unit price = quantity. Did you talk about this formula in the second volume of Senior Two?
I talked about it. According to the content of the second-grade mathematics book published by People's Education Publishing House in 2023, the 22nd page of the book is about what quantity is, and the formula is that the total price divided by the unit price equals quantity, so I talked about it. The second grade is an important transition stage for children's study habits and attitudes to change from plasticity to gradual stereotypes.
