Question

用7,7,3,负3算二十四点

Answer 1

这个很多方式，但原理就一条24/7*7=24，而24/7=3+3/7，所以，只要将3和-3变换顺序加括号就有很多出来了：
7*((3/7)-(-3))=24
7*(3-(-3)/7)=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
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
(3/7-(-3))*7=24
((3/7)-(-3))*7=24

Answer 2

7×【(3÷7)-(-3)】=24

Answer 3

7*(3-(-3)/7)=24
7*(3-((-3)/7))=24
7*(3/7-(-3))=24
7*((3/7)-(-3))=24
(3/7-(-3))*7=24
((3/7)-(-3))*7=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
7*(3/7-(-3))=24
7*((3/7)-(-3))=24
7*(3-(-3)/7)=24
7*(3-((-3)/7))=24

Answer 4

(3 -(-3) ÷ 7) × 7
