MathText

A TeX-spaced source sequence. It parses string children, classifies atoms, cancels unary binary operators, and inserts the appropriate glue. Use MathChoice for four style-dependent child branches.

Property	Default	Meaning
children	Empty	TeX source, math elements, or an array of both.
style	Inherited or "text"	Math style; script styles scale once and use tight spacing.
size_index	Inherited or 6	TeX size declaration; selects its own text/script/scriptscript size table.
strut	false	Add a one-em minimum line box.
klass / left / right	Sequence edges	Overrides turn a nested sequence into a grouped atom.
macros	Empty	Local map from TeX command names to replacement strings.
warnings	"error"	KaTeX compatibility warnings: error, warn, or ignore.
on_error	"throw"	Throw a typed formula error, or render a visible diagnostic.

Common font, color, and sizing properties follow Gum units. Math preserves separate logical advance, outline ink, baseline, and math-axis guides. See math authoring for supported TeX and font setup.
