MathGroup: In methodically reviewing everything I've read in the Mathematica Book, I realized an important undefined term first makes its appearance in "1.4.7 Picking Out Pieces of Algebraic Expressions". Definitions are there for Coefficient[expr,form] and Exponent[expr,form]. The term "expr" has been previously discussed, but the term "form" starts to be used at this point without any prior definition I can find. Does Mathematica have a formal definition for "form"? Where may I find it? Thanks. Harold
