(4*4)-(4/4)
One possible solution is: 4.4 + 4 / .4 = 21
4/4 x 4 =16/4 = simplest form = 4
Google "Four Fours" and you will find a number of solutions, presented more comprehensively than we can.
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!
Only if you subtract three.

To get 7 using only 4 fours, you can use the following mathematical expression: (4 + 4) / (4 / 4) = 8 / 1 = 8. Then subtract 1 from 8 to get 7. This solution involves basic arithmetic operations and the constraint of using only four instances of the number four.
Foals kneel down on all fours when they sleep. Sometimes you might see a dog do it as well.
It could be: 4+40+40 = 6
It could be: 4+4+4-40 = 11
