Ever since Version 3 of Mathematica, there has been rich support for arbitrary mathematical typesetting and layout. Underlying all that power was a so-called box language, ...

Grid[{{expr_11, expr_12, ...}, {expr_21, expr_22, ...}, ...}] is an object that formats with the expr_ij arranged in a two-dimensional grid.

Cot[z] gives the cotangent of z.

PairedHistogram[{x_1, x_2, ...}, {y_1, y_2, ...}] plots a paired histogram of the values x_i and y_i.PairedHistogram[{x_1, x_2, ...}, {y_1, y_2, ...}, bspec] plots a paired ...

ToPackedArray[expr] uses packed arrays if possible in the internal representation of expr.

BoxExtraSpacing is an option for BoxWhiskerPlot which specifies spacing adjustments to be applied when plotting multiple boxes.

PlotDirection is an option for PairwiseScatterPlot which specifies the direction in which scatter plots are generated.

Starting in Version 7, Mathematica includes expression-to-speech functionality. In principle, any Mathematica expression can be translated in this way.

The ability to define and use your own functions is part of what gives Mathematica such power. It is often inconvenient to have to explicitly name a function for every small ...

AlignmentPoint is an option which specifies how objects should by default be aligned when they appear in Inset.
