(4*4)-(4/4)
4+4(4-4)
One possible solution is: 4.4 + 4 / .4 = 21
As a solution to the four fours problem (using the number four no more than four times to come up with the solution, 31 is equal to (4!+4)/4+4!
(4/.4)+4+4 or (44x.4)+.4
(4*4)-(4/4)
4+4(4-4)
Using four fours, you can get 19 with the following sum: 4! - 4 - (4 / 4) That is, four factorial minus four - (four divided by four) - 24 - 4 - (4 / 4) = 19
One possible solution is: 4.4 + 4 / .4 = 21
(4!/4)4 - 4
4 /5
4/4+4/-4
(4+4)/4 + 4 =6
-4-4+4/4
44 + 4/4
As a solution to the four fours problem (using the number four no more than four times to come up with the solution, 31 is equal to (4!+4)/4+4!
4 x 4 + 4/4 = 17
