1 = 44 / 44

2 = 4 * 4 / (4 + 4)

3 = (4 + 4 + 4) / 4

4 = 4 + (4 * (4 - 4))

5 = (4 + (4 * 4)) / 4

6 = 4 + ((4 + 4) / 4)

7 = (44 / 4) - 4

8 = 4 + 4 + 4 - 4

9 = 4 + 4 + (4 / 4)

10 = (44 - 4) / 4

11 = (4 / 4) + (4 / .4)

12 = (4 + 44) / 4

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

14 = (4 * (4 - .4)) - .4

15 = 4 + (44 / 4)

16 = (44 - 4) * .4

17 = (4 * 4) + (4 / 4)

18 = (44 * .4) + .4

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

20 = 4 * (4 + (4 / 4))

To get the number 13 using only four 4s, you can use the following mathematical expression: (4 + 4) + (4 / 4) = 8 + 1 = 9. Then, you can raise 4 to the power of the result: 4^9 = 262144. Finally, take the square root of that result to get 512. Subtract 499 from 512 to get 13.
