This is a textbook for the 5th grade, focusing on comprehensive math problems, ideal for preparing for junior high school entrance exams. Some problems have been marked with a circle if they were answered incorrectly, but I have erased the answers after solving them. I apologize if there are any remaining marks (><) The cover and back cover have pencil marks. Some parts have been reinforced with tape. The name on the back will be hidden if it cannot be erased. Please refrain from purchasing if you are sensitive to used items.
