27 = (-1 + 4)! * 9/2
31 = 1 * 4! + 9 - 2
45 = 1/.4 * 9 * 2 = 1^4 * 9/.2
57 = -1 * 4! + 9²
58 = 1 - 4! + 9²
69 = -1 + 4!*√9 - 2
70 = 1 * 4!*√9 - 2
79 = -1*√4 + 9²
80 = -(1^4) + 9² = (1 + 4! - 9)/.2
83 = 1 * √4 + 9²

Skip, you missed 68; no charge:

-1 + 4! + 9/.2 = 68

Just got "to 100" : 1*T(4) + T(9)*2 = 1*10 + 45*2 = 100

T = Triangular number...

I can't believe I repeated my lame joke twice without effect. OP said: "construct all numbers from 1 to 100!"

...so you meant "100!" ; but that's only a 158 digits number

100 = (1 + 49)*2

There are slips in those.
49 = 1 * (√49)²
59 = -1 + 4√9 / .2 = 14 + 9 / .2

The 90's!

1 * √4 * 9 / .2 = 90
1 + √4 * 9 / .2 = 91
1 + T(4) +9^2 = 92
1 + √4 * T(9) + 2 = 93
1 + √4 * T(9) + T(2) = 94
-1 - 4! + (√9 + 2)! = 95
-1 * 4! + (√9 + 2)! = 96
1 - 4! + (√9 + 2)! = 97
-1dozen + 4 + 9dozen - 2 = 98
-1 + T(4) + T(9) * 2 = 99

Thank you guys! But you missed one other number........ 55.. if you could find anything, that would be nice. There is also another way to make 98 Denis, which does not require dozen.... 1*49*2 and 94: 1* squrt4+92

Shoot! I thought 14, 49, 92, 149 and 492 could not be used...

T(-1+4+9-2) = 55
