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.

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.
It could be: 4+40+40 = 6
Foals kneel down on all fours when they sleep. Sometimes you might see a dog do it as well.
