4x4

44 + 4! + sqrt(4) = 70

arctan(degrees)[4/4] + 4! + sqrt(4) = 71

4!x(4 - 4/4) = 72

arctan(degrees)[4/4] + 4! + 4 = 73

arcSin(degrees)[sqrt(4)/4]/sqrt(4) - 4 = 71

using arcsin(0.5) = 150 degrees as opposed to the principal value of 30


oops!...too slow

4! + 4! + 4! + sqrt(4) = 74

arctan(degrees)[4/4] + arcSin(degrees)[sqrt(4)/4] = 75

arcCos(degrees)[sqrt(4)/4] + 4*4 = 76

(arcSin(degrees)[sqrt(4)/4] + 4)/sqrt(4) = 77

using arcsin(0.5) = 150 degrees as opposed to the principal value of 30

arcCos(degrees)[4-4] - 4!/sqrt(4) = 78

arcSin(degrees)[sqrt(4)/4]/sqrt(4) + 4 = 79

using arcsin(0.5) = 150 degrees as opposed to the principal value of 30

BTW, what number are we going to? 4444!?

arcCos(degrees)[sqrt(4)/4] + (4! - 4) = 80

(4-(4/4))^4 = 81

4! * 4 - 4 * 4 = 80
