 Math & Counting Operations on Lists Ordinary mathematical functions in Mathematica are always "listable", so that they are immediately applied in parallel across lists. Mathematica provides a wide variety of tightly integrated functions for analyzing elements in lists of any size and structure. {..}+{..}, etc. — automatically operate in parallel on list elements Listable — attribute carried by math functions specifying automatic threading over lists      Length — number of elements in a list Total — total from adding up elements in a list      Count — count how many elements match a pattern Tally — tally the number of copies of each distinct element BinCounts — count the number of elements in a sequence of bins                Set-Oriented Operations      TUTORIALS Operations on Scalars, Vectors and Matrices Manipulating Expressions like Lists Testing and Searching List Elements Basic Statistics Partitioning Data into Clusters MORE ABOUT Handling Numerical Data Discrete Mathematics RELATED LINKS How to: Perform Calculations on Columns of Data
