Oops. The input was actually (1+x)^1000000000000000000000 +O[x]^3//Normal//Timing This took "zero" time to evaluate, so we can safely assume that Mathematica drops the O[x]^3 terms as it goes along. -- Stephen P Luttrell QinetiQ, Malvern, U.K. "Stephen P Luttrell" <luttrell at signal.dra.hmg.gb> wrote in message news:9kdbfr$f2m$1 at smc.vnet.net... > and I got this result using Mathematica 4.1 (Windows NT 4): > > (1+x)^1000000 +O[x]^3//Normal//Timing > > {0.Second, 1 + 1000000000000000000000 x + > 499999999999999999999500000000000000000000 x^2}
