One of the benefits of redundancy is error-trapping. If you see a list
of numbers like this:

   40
   14
   24
   56
   48
   12
   60
   16
=====
  269

then you know the result can't be right, because they're all even
numbers and the total isn't. The redundancy of having both the string
of numbers and the total adds only a small amount to the transmission
requirement, but it adds a lot to the reliability of transfer.
