Five of a Kind (Posted on 2003-08-28) Difficulty: 3 of 5
  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.

If we consider the following numbers are to Base 7 then we have:

44 x 4/4 + 4 + 4 = 55

44 Base 7 is 32 Base 10
55 Base 7 is 40 Base 10
