1. A puzzle book challenged its readers to form an expression using five threes and basic mathematical symbols to come up with 37.
   The answer was found simply enough:
   
   33 + 3 + 3/3 = 37.
   
   Find another way to do this.
   
   
2. The same puzzle book posed the problem of finding 55 using five fours and any mathematical symbols.
   That is also easily accomplished by:
   
   44 + 44/4 = 55.
   
   Find another way to do this one, as well.

Well, I origially also planned to give solution to 4s but I couldn't when got to it - and I reckon it's impossible with only using 4 basic signs. It seems to be cheating to use ! and other signs (and I include bar in that) ;)

Also needed some posts so can become a student (not again) and place a few puzzles I have.
