(1) 3, 8, 12, 10 这四个数的运算结果为24

(2) 2,9, 3, 4 这四个数的运算结果为-24

(1)方法1:10/(8-3)*12
方法2:12/(8-3)*10=24

(2)方法1:(2-4)*(3+9)=-24
方法2:3*(3-9-2)

1:1: (12 ÷ (8 - 3)) × 10
2: 12 ÷ (8 - 3) × 10
3: 12 ÷ ((8 - 3) ÷ 10)
4: 12 × (10 ÷ (8 - 3))
5: 12 × 10 ÷(8 - 3)
6: (12 × 10) ÷ (8 - 3)
7: (10 ÷ (8 - 3)) × 12
8: 10 ÷ (8 - 3) × 12
9: 10 ÷ ((8 - 3) ÷ 12)
10: 10 × (12 ÷ (8 - 3))
11: 10 × 12 ÷(8 - 3)
12: (10 × 12) ÷ (8 - 3)
2:1: 2 × 9 ÷ 3 × 4
2: (2 × 9) ÷ 3 × 4
3: (2 × 9 ÷ 3) × 4
4: ((2 × 9) ÷ 3) × 4
5: (2 × (9 ÷ 3)) × 4
6: 2 × (9 ÷ 3) × 4
7: 2 × (9 ÷ 3 × 4)
8: 2 × ((9 ÷ 3) × 4)
9: 2 × (9 ÷ (3 ÷ 4))
10: 2 × 9 ÷(3 ÷ 4)
虽然是正数,你自己改一下!!!!!

10/(8-3)*12

3*(3-9-2)

第一个,12/(8-3)*10=24
第二个,(2-4)*(3+9)=-24
