I'm a little confused by these results.  Perhaps someone can tell me
what I'm assuming incorrectly:

  $ irb
  irb(main):001:0> 5 / 9 * ( 100 - 32 )
  => 0
  irb(main):002:0> ( 5 / 9 ) * ( 100 - 32 )
  => 0
  irb(main):004:0> ( 100 - 32 ) * ( 5 / 9 )
  => 0
  irb(main):003:0> ( 100 - 32 ) * 5 / 9
  => 37

The last result is the only one that gives me what I actually wanted.

In case you're wondering, yes, that *is* an F-to-C temperature
conversion.
