算24点给你4 4 8 9

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

(9-4-2)*8

(4-(10-9))*8 ((4-10)+9)*8 ((4+9)-10)*8 (4+(9-10))*8 8*(4-(10-9)) 8*((4-10)+9) 8*((4+9)-10) 8*(4+(9-10)) 8*((9+4)-10) 8*(9+(4-10)) 8*(9-(10-4)) 8*((9-10)+4) ((9+4)-10)*8 (9+(4-10))*8 (9-(10-4))*8 ((9-10)+4)*8

(1)(4–9÷9)×8=24 (2) 8×(4–9÷9)=24

你好!用3,4,8,9算24点,共有144种算法。 [9+﹙4+3﹚]+8 [9+﹙8+4﹚]+3 3+[4+﹙9+8﹚] ﹙4+9﹚+﹙8+3﹚ [8+﹙9+4﹚]+3 8×[﹙3+9﹚÷4] 9+[﹙8+4﹚+3] 3+[﹙4+9﹚+8] 4+[8+﹙9+3﹚] [8+﹙4+3﹚]+9 [8×﹙9+3﹚]÷4 8+...

共有四种不同算法,举例如下: 4+3+8+9=24 (9+3)×8÷4=24

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

8×4-9+1 =32-9+1 =23+1 =24

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