11 = (42 - 4) - (4 / 4)

12 = (4 + 4) + (√4 + √4)

13 = (42 - 4) + (4 / 4)

14 = (4 + 4 + 4 + √4)

15 = (4 * 4) - (4 / 4)

16 = (4 + 4 + 4 + 4)

17 = (42 + √4) - (4 / 4)

18 = (42 + 4) - (4 - √4)

19 = (42 + 4) - (4 / 4)

20 = (4 * 4) + (√4 + √4)

You can't unless something is missing in your question.

3*3*2*1 = 18 of them.

Using only sums and differences, and not necessarily all four numbers, 1, 3, 9 and 27 will make all numbers from 0 to 40.
