- 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. - 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.
