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 mathematical constructs.Complicated expressions can be built by working in ConTeXt|LaTeX equations in ConTeXt]] with a relatively small set of supporting definitionssteps---break down the expression into sub-expressions, build the sub-expressions and then combine them to get the complicated expression.* The "native" ConTeXt way basics of typesetting math in ConTeXt is [[MathML]], an application of [[XML]] - rather verbose but mightyexplained here.

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>. == 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] by Adam Lindsayfor 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]].
