20: 6 × ((5 + 3) - 4)
21: 6 × (5 + (3 - 4))
22: 6 × (5 - 4 + 3)
23: 6 × ((5 - 4) + 3)
24: 6 × (5 - (4 - 3))

那不是越算越小吗？

6*((3-4)+5)=24
6*(3-(4-5))=24
6*(3+5-4)=24
6*((3+5)-4)=24
6*(3+(5-4))=24
6*(5+3-4)=24
6*((5+3)-4)=24
6*(5+(3-4))=24
6*(5-4+3)=24
6*((5-4)+3)=24
6*(5-(4-3))=24
(5+3-4)*6=24
((5+3)-4)*6=24
(5+(3-4))*6=24
(5-4+3)*6=24
((5-4)+3)*6=24

讲真的，这题无
