Answer 1

1:2 × (3 - 2 + 11)

2:2 × ((3 - 2) + 11)

3:2 × (3 - (2 - 11))

4:2 × (3 + 11 - 2)

5:2 × ((3 + 11) - 2)

6:2 × (3 + (11 - 2))

7:2 × (11 - 2 + 3)

8:2 × ((11 - 2) + 3)

9:2 × (11 - (2 - 3))

10:2 × (11 + 3 - 2)

11:2 × ((11 + 3) - 2)

12:2 × (11 + (3 - 2))

13:(3 - 2 + 11) × 2

14:((3 - 2) + 11) × 2

15:(3 - (2 - 11)) × 2

16:(3 + 11 - 2) × 2

17:((3 + 11) - 2) × 2

18:(3 + (11 - 2)) × 2

19:(11 - 2 + 3) × 2

20:((11 - 2) + 3) × 2

21:(11 - (2 - 3)) × 2

22:(11 + 3 - 2) × 2

23:((11 + 3) - 2) × 2

24:(11 + (3 - 2)) × 2
