* There are two different math modules TeX was designed for ease of typesetting books that contained mathematics. As ConTeXt is built on [http://dante.ctan.org/tex-archive/macros/context/contrib/maths/ CTAN]top of TeX, [[Math with nath|nath]] and [[Math with amsl|amsl]]it inherits all those features.* It is also possible In addition to use most [[LaTeX Math in these, ConTeXt|LaTeX equations in ConTeXt]] with a relatively small set adds lot of macros to make the typesetting of supporting definitionsmathematics easier.* The "native" ConTeXt way There are '''two''' kinds of '''math is [[MathML]], an application of [[XML]] modes''' --- rather verbose but mighty'''inline math and display math'''.* And there's a [[Math Mathematical expressions that are written with newmat|new the running text are called inline math; while mathematical expressions that break the flow of the text (such as formulas or equations) are called display math]] module . TeX takes care of proper spacing around expressions and provides macros to typeset most mathematical constructs.Complicated expressions can be built by working in steps---break down the expression into sub-expressions, build the sub-expressions and then combine them to get the distributioncomplicated expression.

ConTeXt supports inline === Display math (mathematical formulas set within ordinary paragraphs as part of the text) and display math (mathematics set on lines by themselves, often with equation numbers). Inline math is enclosed in "$" signs, while display math is enclosed in a <cmd>startformula</cmd> / <cmd>stopformula</cmd> pair.mode ===Type

Inline math is set as $c^2 = a^2 + b^2$, and display math as\placeformula\startformulac^2 = a^2 + b^2... \stopformula

This, when typeset, produces the followingto get display math mode. === Inline math mode ===There are four equivalent commands to get inline math mode:

<contexttexcode>Inline math is set as $c^2 = a^2 + b^2... $, and display math as % TeX style.\placeformulam{ ... } \startformulac^2 = a^2 + b^2math{ ...} \stopformulamathematics{ ... }</contexttexcode>

The === 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 <cmdcode>placeformula$$ .... $$</cmdcode> command is optional''' to write display math formulas in ConTeXt, and produces since you will not get the equation number; leaving it off produces an unnumbered equationcorrect spacing around the formulas.Instead use

A more complicated equation:\placeformula\startformula{{\theta_{\text{ConTeXt}}}^2 \over x+2} = \pmatrix{a_{11}&a_{12}&\ldots&a_{1n}\cr a_{21}&a_{22}&\ldots&a_{2n}\cr \vdots&\vdots&\ddots&\vdots\cr a_{n1}&a_{n2}&\ldots&a_{nn}\cr} \pmatrix{b_1 \cr b_2 \cr \vdots \cr b_n} + \sum_{j=1}^\infty z^j \left( \sum_{\scriptstyle n=1 \atop \scriptstyle n \ne j}^\infty Z_j^n \right)... \stopformula

which produces<context>A See [[Math/Display]] for more complicated equation:\placeformula\startformula{{\theta_{\text{details on how to use display math in ConTeXt}}}^2 \over x+2} = \pmatrix{a_{11}&a_{12}&\ldots&a_{1n}\cr a_{21}&a_{22}&\ldots&a_{2n}\cr \vdots&\vdots&\ddots&\vdots\cr a_{n1}&a_{n2}&\ldots&a_{nn}\cr} \pmatrix{b_1 \cr b_2 \cr \vdots \cr b_n} + \sum_{j=1}^\infty z^j \left( \sum_{\scriptstyle n=1 \atop \scriptstyle n \ne j}^\infty Z_j^n \right)\stopformula</context>.

=== 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://wwwdl.ntgcontextgarden.nl:8061net/myway/texmathcontext-latex-math.pdf HereMy Way] for how to 'translate' from amsmath syntax to ConTeXt syntax. [[LaTeX_Math_in_ConTeXt]] you can try it "live" (PDF interface!)gives some brief ideas on how to get the LaTeX syntax to run in ConTeXt.

What's going == Other Methods ==* There are two different math modules on here is simpler than it might appear at first glance[http://dante.ctan. Both <cmd>placeformula<org/cmd> tex-archive/macros/context/contrib/maths/ CTAN], [[Math with nath|nath]] and <cmd>placesubformula</cmd> produce equation numbers [[Math with amsl|amsl]]. And there's a [[Math with newmat|new math]] module in the optional tag added at the end; the sole difference 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.* The "native" ConTeXt way of math is that the former increments the equation number first[[MathML]], while the latter does not (and thus can be used for the second and subsequent formulas that use the same formula number an application of [[XML]] - rather verbose but presumably have different tags)mighty.

There's a special command, <{{cmd>|digits</cmd>}}, and a with its own manual about formatting numbers, see [http://www.pragma-ade.comnl/general/magazines/mag-0003.pdf Pasting digits together]
