? The charming summer vacation is coming, and the math homework supermarket is about to open. Please consult your family to choose "goods" and choose at least three kinds of homework. No.4 is a must for everyone, 1 is a must for B students, and No.2 is a must for miscalculation in the final exam. Although the number of purchases is "not capped", rest and activities are also important.
