3,-3,7,7四个数玩24点,
答
(3--3÷7)×7=24
(3÷7--3)×7=24
7×(3--3÷7)=24
7×(3÷7--3)=24
(3-(-3)/7)*7=24 (3-((-3)/7))*7=24 (3-(-3)/7)*7=24 (3-((-3)/7))*7=24 (3/7-(-3))*7=24 ((3/7)-(-3))*7=24 (3/7-(-3))*7=24 ((3/7)-(-3))*7=24 7*(3-(-3)/7)=24 7*(3-((-3)/7))=24 7*(3/7-(-3))=24 7*((3/7)-(-3))=24 7*(3-(-3)/7)=24 7*(3-((-3)/7))=24 7*(3/7-(-3))=24 7*((3/7)-(-3))=24
