2,3,4,5算24点怎么算?

1.3+5=8,8-2=6,4×6=24 2.3+4+5=12,12×2=24

可以是 (3+4+5)×2=24 (3+5-2)×4=24

解法如下; (1)3×(5×2-2)=24 (2)(5×2-2)×3=24 科学型: (5-2÷2)×3!=24(4!=24)

1: 2 × (3 + 4 + 5) 2: 2 × ((3 + 4) + 5) 3: 2 × (3 + (4 + 5)) 4: 2 × (3 + 5 + 4) 5: 2 × ((3 + 5) + 4) 6: 2 × (3 + (5 + 4)) 7: 2 × (4 + 3 + 5) 8: 2 × ((4 + 3) + 5) 9: 2 × (4 + (3 + 5)) 10: 2 × (4 + 5 + 3) 11: 2 × ((4 + 5) + 3) 12...

36个解 (-2)*((-3)-(4+5))=24 (-2)*((-3)-4-5)=24 (-2)*(((-3)-4)-5)=24 ((-2)-(-3)+5)*4=24 (((-2)-(-3))+5)*4=24 ((-2)-((-3)-5))*4=24 (-2)*((-3)-(5+4))=24 (-2)*((-3)-5-4)=24 (-2)*(((-3)-5)-4)=24 ((-2)+5-(-3))*4=24 (((-2)+5)-(-3))*4=...

2*5+3*4

(5+2)×3+3=24

(-3)*(-5)-2-4+(-3)*(-5)=24 用-3.-5.2和4 (-3)*(-5)+6+6/2=24用-3.-5.6和2 如果不规定选定的数一个只能用一次的话有太多种答案了

5,2,3,4答案 (5-(2-3))*4 ((5-2)+3)*4 ((5+3)-2)*4 (5+(3-2))*4 ((5+3)+4)*2 (5+(3+4))*2 ((5+4)+3)*2 (5+(4+3))*2 2*((5+3)+4) 2*(5+(3+4)) 2*((5+4)+3) 2*(5+(4+3)) 2*((3+5)+4) 2*(3+(5+4)) 2*((3+4)+5) 2*(3+(4+5)) 2*((4+5)+3) 2*(4+(5+...

1. [﹙4+5﹚+3]×2 2. [﹙5+3﹚-2]×4 3. [﹙3+5﹚-2]×4
