2.2.11.11.怎么算24点

你好!用2,2,11,11算24点,共有4种算法。 [﹙2÷11﹚+2]×11 [2+﹙2÷11﹚]×11 11×[﹙2÷11﹚+2] 11×[2+﹙2÷11﹚]

每个数只能用一次吗?

[﹙2÷11﹚+2]×11=24

(11+11-10)×2 =12×2 =24

1: (2 + 2 ÷ 11) × 11 2: (2 + (2 ÷ 11)) × 11 3: (2 ÷ 11 + 2) × 11 4: ((2 ÷ 11) + 2) × 11 5: 11 × (2 + 2 ÷ 11) 6: 11 × (2 + (2 ÷ 11)) 7: 11 × (2 ÷ 11 + 2) 8: 11 × ((2 ÷ 11) + 2)

共有48种解法,下面是其中的8种: 更多解法只要移动1的位置或/和把1×或×1中乘号改成除号就能得到 (1)11×2+2×1=24 (2)2×11+2×1=24 (3)11×2+1×2=24 (4)2×11+1×2=24 (5)1×2+11×2=24 (6)2×1+11×2=24 (7)1×2+2×11=24 (8)2×1+2×11=24

(2+(2/11))x 11 = (24 /11) x 11 =24 /表示除号

((3*11)+2)-11 (3*11)+(2-11) (3*11)-(11-2) ((3*11)-11)+2 ((3*11)+2)-11 (3*11)+(2-11) (3*11)-(11-2) ((3*11)-11)+2 2+((3*11)-11) (2+(3*11))-11 2+((3*11)-11) (2+(3*11))-11 2-(11-(3*11)) (2-11)+(3*11) 2+((11*3)-11) (2+(11*3))-11 2-(...

((6+11)*2)-10 ((6/2)+11)+10 (6/2)+(11+10) ((6/2)+10)+11 (6/2)+(10+11) 11+((6/2)+10) (11+(6/2))+10 ((11+6)*2)-10 11+(10+(6/2)) (11+10)+(6/2) 10+((6/2)+11) (10+(6/2))+11 10+(11+(6/2)) (10+11)+(6/2) (2*(6+11))-10 (2*(11+6))-10
