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

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
