Power series are represented in Mathematica as SeriesData objects. The power series is printed out as a sum of terms, ending with O[x] raised to a power. Internally, however, ...

Expressions in Mathematica can be represented as strings in a variety of ways, for display, export, or processing. Mathematica provides powerful functions for formatting ...

While there is typically one representation for exact numbers, approximate numbers can be presented differently according to the conventions of different professions or ...

Mathematica uses its symbolic architecture to provide a convenient modular framework for generating and managing messages, both in programs and interactive sessions.

Mathematica does operations like numerical integration very differently from the way it does their symbolic counterparts. When you do a symbolic integral, Mathematica takes ...

When summarizing data, it is often useful to analyze it by subgroup. For example, crop yields could be categorized by seed variety, or average patient recovery time by ...

Like everything else in Mathematica, notebooks are ultimately symbolic expressions. When you edit notebooks—or apply high-level programmatic functions—Mathematica ...

LayeredGraphPlot attempts to draw the vertices of a graph in a series of layers, placing dominant vertices at the top, and vertices lower in the hierarchy progressively ...

DefaultElement is an option for Grid and related constructs which specifies what to insert when a new element is interactively created.

$ProcessorCount gives the number of processor cores available on the computer system on which Mathematica is being run.
