用5,4,9,3凑24点

4×【5×3-9】 =4×6 =24 ~一刻永远523为你解答,祝你学习进步~~~ ~如果你认可我

(3-9)*(5-9) (3-9)*(5-9) (9-3)*(9-5) (9/(3/5))+9

(-5)*(-9)-3*7=24

8x3x(5-4)=24 (8+4)x(5-3)=24 8x4x(5+3)=24

(5+9-8)*4 (5+(9-8))*4 ((5+9)-8)*4 8+(9-5)*4 8+

3×4×[-3-(-5)] =12×2 =24

1. [5+9×2]-4 2. 4+2×9-5

1: (4 - 1) × 5 + 9 2: ((4 - 1) × 5) + 9 3: (5

(9-5÷5)×3=8×3=24故答案为:(9-5÷5)×3.

这四个数算24点如果只用加减乘除四则运算共有两种算法: 如果用上根号或阶乘等其它运算规则就有多种算
