9.11.11.12算24点

解:11-9=2 2×12=24

这个无解 9 11 13 12倒是很多解 1:(9 + 13) ÷ 11 × 12 2:((9 + 13) ÷ 11) × 12 3:(9 + 13) ÷ (11 ÷ 12) 4:(9 + 13) × 12 ÷ 11 5:((9 + 13) × 12) ÷ 11 6:(9 + 13) × (12 ÷ 11) 7:(12 × (9 + 13)) ÷ 11 8:12 × (9 + 13) ÷ 11 9:12 × ((9 + 13) ÷ ...

11×12-9×12=24

(9+11)/(10/12) ((9+11)/10)*12 ((9+11)*12)/10 (9+11)*(12/10) 10-((9-11)-12)

1: (9 + 13) ÷ 11 × 12 2: ((9 + 13) ÷ 11) × 12 3: (9 + 13) ÷ (11 ÷ 12) 4: (9 + 13) × 12 ÷ 11 5: ((9 + 13) × 12) ÷ 11 6: (9 + 13) × (12 ÷ 11) 7: (12 × (9 + 13)) ÷ 11 8: 12 × (9 + 13) ÷ 11 9: 12 × ((9 + 13) ÷ 11) 10: 12 ÷ 11 ×(9 +...

(11-9)X12 =2X12 =24

3、1、9、11 3x1x11-9 =33-9 =24 3x11÷1-9 =33-9 =24; 3x11-9÷1 =33-9 =24; 3+1+9+11 =24; …… 2、11、4、12 4x(11-2)-12 =4x9-12 =36-12 =24. 供参考。

(7)2*9+(7-1) (8)9/3*(1+7) (9)(2 × 7 - 6) × 3 (10)2 × 9 - 2 + 8 (11)(1 × 2 + 6) × 3 (12) 5 × (5 - 1 ÷ 5) (13)(2 - 5 + 7) × 6 (14)(3 + 9 ÷ 5) × 5 (15)(6 × (6 - 1)) - 6 (16)10 - 6 + 10 + 10 (17)3 - 7 ×(7 ...

(8×11+8)/4=24 (4+4)×(12-9)=24 (9+9-12)×4=248

1.10/(11-9)+19=24 2.6/9x15+14=24 3.12/(8-15/2)=24 请及时采纳
