< [[Main Page]] | [[Math with newmat]] | [[MathML]] | [[Multiline equations]]> == Introduction ==
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.
=== Display math mode ===
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>
'''See [[Math/Display]] for more details''' on how to use display math in ConTeXt:* numbering* referencing* sub-formulae* list of Formulae* formating === 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.
</context>
=== 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>.

'''s a special commandDo 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|digitsstartformula}}, with its own manual about formatting numbers, see [http://www.pragma-ade.nl/general/magazinesand <tt>\stopformula</mag-0003tt>.pdf Pasting digits together]
