=== Display math mode ===
=== Inline math mode ===
=== Note to Plain TeX Users ===
ConTeXt is plain TeX compatible. So, if you have any old document written in plain TeX, it will work with ConTeXt. This does not mean that you will get pixel by pixel identical output with ConTeXt. For inline math, everything that you learnt for plain TeX is also true for ConTeXt. However, display math is significantly different. '''Do not use <code>$$ .... $$</code>''' to write display math formulas in ConTeXt, since you will not get the correct spacing around the formulas. Instead use {{cmd|startformula}} and <tt>\stopformula</tt>.
See For examples<code>$x$</code> gives <context>\setuplayout[scale=0.8]$x$</context>, while<code>$2$</code> gives <context>\setuplayout[scale=0.8]$2$</context>.Notice that the ''x'' is in italic while the ''2'' is upright. This is the usual mathematic convention. = Formula, formulae, equations = * '''[[Math/Display| Math display]]'''** numbering** referencing** sub-formulae** list of Formulae** formating* '''[[Math/Multiline_equations | Multiline equations]] for more details on how '''** alignment** number of columns** equation numbering and sub-numbering (very similar to use display math in ConTeXt.above)** formating, specifying and defining alignment** cases* '''[[Math/Matrices| Matrices]]'''** definition** delimiters** block matrices and vertical/ horizontal lines** border matrices

→Formula, formulae, equations
TeX was designed for ease of typesetting books that contained mathematics. As ConTeXt is built on top of TeX, it inherits all those features. In addition to these, ConTeXt adds lot of macros to make the typesetting of mathematics easier.
The basics of typesetting math in ConTeXt is explained here.
Type {{cmd|startformula}} to get display math mode, or {{cmd|dm}} to get a inline typesetting but keeping display sizing and rules.
<context source="yes">
c^2 = a^2 + b^2.
\stopformula
\dm{c^2 = a^2 + b^2}
</context>
There are four equivalent commands to get inline math mode: {{cmd|$}}, {{cmd|m}}, {{cmd|math}}, {{cmd|mathematics}} to get display inline math mode.

=Typesetting Math == Note to AMSTeX/LaTeX Users ===ConTeXt offers almost all the features that are present in AMSTeX and LaTeX. However, ConTeXt syntax is different. See this [http://dl.contextgarden.net/myway/context-latex-math.pdf My Way] for how to 'translate' from amsmath syntax to ConTeXt syntax. [[LaTeX_Math_in_ConTeXt]] gives some brief ideas on how to get the LaTeX syntax to run in ConTeXt.

== Other Methods ==
* The "native" ConTeXt way of math is [[MathML]], an application of [[XML]] - rather verbose but mighty.* There are two different math modules on [http://dante.ctan.org/tex-archive/macros/context/contrib/maths/ CTAN], [[Math with nath|nath]] and [[Math with amsl|amsl]]. And there's a [[Math with newmat|new mathmodule]] module in the distribution.* Context now has inbuilt support for [[Multiline equations]]
* It is also possible to use most [[LaTeX Math in ConTeXt|LaTeX equations in ConTeXt]] with a relatively small set of supporting definitions.
==ScienceTo do ==* Esp. for physics there’s the [[Units]] module.* Additions to [[MathML]] are PhysML and ChemML.dots* [[Chemistry]]* There's a module for chemical structure formulae: [[Chemistry|PPCHTeX]] Arrows (works also with LaTeX). ==Number Formatting==There's a special command, {{cmd|digits}}, with its own manual about formatting numbers, see [http://wwwdl.pragma-adecontextgarden.nlnet/generalmyway/magazines/mag-0003matharrows.pdf Pasting digits togetherMath Arrows] ==Evaluating expressions in ConTeXt==(i.e. ''doing'' math)broken link* See also [[Expressions]].{{todo|}}
