This is a textbook I purchased in the second half of fourth grade. Please check the photos for the scope of the content. There are some check marks, etc., in the places marked with an "x," but I have erased them after solving the problems. I apologize if I missed any (><) If I can't erase the name on the back, I will cover it before sending. Please refrain from purchasing if you are sensitive to used items. *I will send it in simple packaging. Please read my profile before purchasing. Thank you. #JuniorHighSchoolEntranceExam #Math #Mabuchi #Textbook
