My use of Mathematica yields expressions with literal parameters that run on for pages. But I know that two or three of the terms in these expressions dominate the rest because I know that (e.g.) p1/p2>>p3/p4. How can I tell Mathematica this and get it to automatically drop p3/p4 from p1/p2 + p3/p4, and p3 from p1 p4/p2 + p3, and (p2 p3)^2 from (p1 p4)^2 + (p2 p3)^2, and p2/p1 from p2/p1 + p4/p3, and 1 from p1 p4/p2/p3 + 1, et al.? --John Pinson
