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.

I like the problem, it's good - I guess feel 'cheated' as spent ages trying to only use 'basic' symbols. Felt ! brought in too many options, and would be more than one more solution.
Don't mean to diss problem. Like this sort, simple operations, lots of possibilities. Another variation of Countdown is always good. (Do you get a version of that in the US?)
