The Four 4's Game

12 = (4 * 4) - ( square root of 4 + square root of 4)

(sorry about words instead of square root symbol...cant find it on my mobile phone)

What I did was to copy and paste the "√" symbol from others posts and pasted it to where I wanted to be. There is an ASCII code (Hold <alt> down while typing the code in on numeric key pad.) for the "√" symbol but I don't know it off hand. You should be able to copy and paste on your mobile device.
 
16 = 4! - (4 * 4) * √4
16 = 4 + 4 - 4 * 4

Showing that's there's more then one way to get the same answer.
 
26 = 4! + √4 + 4 - 4
(I think that 31 & 33 are going to be the next hard ones.)
