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))
Only if you subtract three.
4! - 44/4 = 24 - 11 = 13
4x + 2 = 54
13
44 * 4/4
(4!/4)4 - 4
4+4(4-4)
4*4*4-(4/4)
(4x4+4)/4
4/4+4/4=2
4! + [(4*4)/4^2]
4 + 4 - (4/4) = 7
