1:(2 + 2 ÷ 3) × 9
2:(2 + (2 ÷ 3)) × 9
3:(2 + 2) × (9 - 3)
4:2 × (2 × (9 - 3))
5:2 × 2 ×(9 - 3)
6:(2 × 2) × (9 - 3)
7:2 × 3 + 2 × 9
8:(2 × 3) + 2 × 9
9:2 × 3 +(2 × 9)
10:(2 × 3) + (2 × 9)
11:(2 ÷ 3 + 2) × 9
12:((2 ÷ 3) + 2) × 9
13:2 × 3 + 9 × 2
14:(2 × 3) + 9 × 2
15:2 × 3 +(9 × 2)
16:(2 × 3) + (9 × 2)
17:2 × 9 + 2 × 3
18:(2 × 9) + 2 × 3
19:2 × 9 +(2 × 3)
20:(2 × 9) + (2 × 3)
21:2 × 9 + 3 × 2
22:(2 × 9) + 3 × 2
23:2 × 9 +(3 × 2)
24:(2 × 9) + (3 × 2)
25:(2 × (9 - 3)) × 2
26:2 × (9 - 3) × 2
27:2 × ((9 - 3) × 2)
28:3 × 2 + 2 × 9
29:(3 × 2) + 2 × 9
30:3 × 2 +(2 × 9)
31:(3 × 2) + (2 × 9)
32:3 × 2 + 9 × 2
33:(3 × 2) + 9 × 2
34:3 × 2 +(9 × 2)
35:(3 × 2) + (9 × 2)
36:3 × (9 - 2 ÷ 2)
37:3 × (9 - (2 ÷ 2))
38:(9 - 2 ÷ 2) × 3
39:(9 - (2 ÷ 2)) × 3
40:9 × 2 + 2 × 3
41:(9 × 2) + 2 × 3

50:9 × (2 ÷ 3 + 2)
51:9 × ((2 ÷ 3) + 2)
52:(9 - 3) × (2 + 2)
53:(9 - 3) × 2 × 2
54:((9 - 3) × 2) × 2
55:(9 - 3) × (2 × 2)
再问: 对不起我们只能在括号填加减乘除而且数字不能变位置只能按2( )2( )3( )9=24
再答: 1: (2 + 2 ÷ 3) × 9 2: (2 + (2 ÷ 3)) × 9
