> Hi, John I rec'd some answers to the questions you had yesterday regarding high order polynomials: Mathematica can handle high order polynomials (100+ for example) and find their multiple roots, though you will in most cases be limited to numeric roots, not symbolic or exact (rational). (Also, this can take a fair amount of time/memory; it will vary depending on the polynomials, etc.) About the infinite loop/sum of rational polynomials: Our tech guy, John, did not know anything that would cause this; he asked if you were just adding some polynomials, or using some other function, such as Solve, that could have large intermediate expressions that would take a very long time to evaluate, giving the appearance of an infinite loop. If it is a simple addition, it should be reported to support at wri.com, maybe there is a bug fix, or maybe it is know and will be fixed shortly, or maybe it needs to be made known.
