Four Fours

Friday! Friday!  To finish off your week with a bang I am sending you a fantastically fun math problem!

Four Fours
How many numbers can you represent using four 4's and any available operation?

For example, here is the representation for the number 0: 
0 = 44 - 44

See how the representation contains four 4's

Find the representation for the numbers 1 through 10.

Enjoy!  And try not to hurt your brain thinking about it!  ;)

Sincerely,
The Math Freak

    1= (4/4)+4-4
    2= (4*4)/(4+4)
    3= (4+4+4)/4
    4= ((4-4)/4)+4
    5= ((4*4)+4)/4
    6= ((4+4)/4)+4
    7= 4+4-(4/4)
    8= 4+4+4-4
    9= 4+4+(4/4)
    10= (44-4)/4

    YAY
