Changes

Many people start with TeX because they want 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 set formulae.Simple math typesetting exists since PlainTeX and these commands work in , ConTeXt as in LaTeX.Advanced math was introduced adds lot of macros to TeX by AMS (American Mathematical Society); nowadays AMSTeX and LaTeX are unitedmake the typesetting of mathematics easier. But how can one use advanced math with ConTeXt?

* There are '''two different ''' kinds of '''math modules on [http://dante.ctan.org/texmodes''' ---archive/macros/context/contrib/maths/ CTAN], [[Math with nath|nath]] '''inline math and [[Math display math'''. Mathematical expressions that are written with amsl|amsl]]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.* It is also possible TeX takes care of proper spacing around expressions and provides macros to use typeset most [[LaTeX Math in ConTeXt|LaTeX equations in ConTeXt]] with a relatively small set of supporting definitionsmathematical constructs.* The "native" ConTeXt way of math is [[MathML]]Complicated expressions can be built by working in steps---break down the expression into sub-expressions, an application of [[XML]] build the sub- rather verbose but mightyexpressions and then combine them to get the complicated expression.* And there's a [[Math with newmat|new The basics of typesetting math]] module in the distributionConTeXt is explained here.

==Simple MathDisplay math mode ==

ConTeXt supports inline math (mathematical formulas set within ordinary paragraphs as part of the text) and Type {{cmd|startformula}} to get display math (mathematics set on lines by themselvesmode, often with equation numbers). Inline math is enclosed in "$" signs, while or {{cmd|dm}} to get a inline typesetting but keeping display math is enclosed in a <cmd>startformula</cmd> / <cmd>stopformula</cmd> pairsizing and rules.

== Inline math mode == There are four equivalent commands to get inline math mode: {{cmd|$}}, {{cmd|m}}, {{cmd|math}}, {{cmd|mathematics}} to get display inline math mode. <contextsource="yes">Inline math \framed[align=normal,frame=off]{%The famous result (once more) is set as given by $c^2 = a^2 + b^2$, and display math as.\par % TeX style.The famous result (once more) is given by \m{c^2 = a^2 + b^2}.\placeformulapar The famous result (once more) is given by \startformulamath{c^2 = a^2 + b^2}.\par The famous result (once more) is given by \stopformulamathematics{c^2 = a^2 + b^2}.}

[http://www== 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>$$ ...ntg.nl:8061$$</texmathcode>''' to write display math formulas in ConTeXt, since you will not get the correct spacing around the formulas.pdf Here] you can try it "live" (PDF interface!)Instead use {{cmd|startformula}} and <tt>\stopformula</tt>.

== 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. [[MathAlignmentLaTeX_Math_in_ConTeXt]] is covered gives some brief ideas on a separate pagehow to get the LaTeX syntax to run in ConTeXt.

==Number FormattingOther Methods ==* The "native" ConTeXt way of math is [[MathML]], an application of [[XML]] - rather verbose but mighty.* There's a special command, <cmd>digits</cmd>, and a own manual about formatting numbers, see are two different math modules on [http://wwwdante.pragmactan.org/tex-ade.comarchive/macros/context/generalcontrib/magazinesmaths/mag-0003CTAN], [[Math with nath|nath]] and [[Math with amsl|amsl]]. And there's a [[Math with newmat|new math module]] in the distribution.pdf Pasting digits together* It is also possible to use most [[LaTeX Math in ConTeXt|LaTeX equations in ConTeXt]]with a relatively small set of supporting definitions.
