4 8 9 9算24点怎么算

(9+4-10)×8=24 (10-8÷4)×√9=24 [8×(10-9)-4]!=4!=24

((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)

4×(9-1)-8=4×8-8=32-8=24 4×8-(9-1)=32-8=24 4×8-9+1=32-9+1=23+1=24 9÷[(4-1)÷8]=9÷(3÷8)=9÷3/8=9×8/3=3×8=24 9÷(4-1)×8=9÷3×8=3×8=24 9×8÷(4-1)=72÷3=24

(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

4×(9-8+5)

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

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

你好! 用4,5,8,9算24点,共有22种算法。 [9-﹙8-5﹚]×4 [﹙9-5﹚×4]+8 [﹙5-8﹚+9]×4 [5+﹙9-8﹚]×4 [4×﹙9-5﹚]+8 4×[﹙5-8﹚+9] 4×[9-﹙8-5﹚] 4×[﹙9-8﹚+5] 8+[﹙9-5﹚×4] [﹙9-8﹚+5]×4 4×[﹙9+5﹚-8] 4×[5+﹙9-8...

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 - ...
