DESCRIPTION:We take a fresh look at an old problem of representing natural
  numbers\nin the lambda-calculus. Our interest is in finding representatio
 ns\nwhere we can compute efficiently (and where possible\, in constant\nti
 me) the following functions: successor\, predecessor\, addition\,\nsubtrac
 tion and test for zero. Surprisingly\, we find a solution in the\nlinear l
 ambda-calculus\, where copying and erasing are not permitted.
