Molly, You are probably obtaining Root objects. These are a somewhat arcane, but exact representation of the roots of a polynomial equation. To find out more about them, and how to convert them to regular numbers, type the following and evaluate: ?*Root* Especially look at Root, and follow the links at the end of the usage messages to the Function Help pages. -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ "Molly Lipscomb" <molly_lipscomb at yahoo.com> wrote in message news:gdevcc$3mp$1 at smc.vnet.net... > Hi, > When I ask Mathematica to solve one of my equations, at first it says that > the response is long, and asks whether I want the full output, or the > output with a size limit.
