(4x4)+(4/4)-4
The above uses five 4's. An answer, using factorials, and only four is:
(4!+4-sqrt(4))/sqrt(4)
yrs
Probably 45$
44-4/4
44 divided by .44
4+4-(4/4)
Google "Four Fours" and you will find a number of solutions, presented more comprehensively than we can.
4+4+(4-4) = 4
The answer is 4! - [(4+4)/4]
(4x4)-(4/4) = 15
4! - 44/4 = 24 - 11 = 13
4!/4 - 4/4 = 5
4+4+4x4 by the power of 0.
