MathML (Mathematics Markup Language) is an XML-based standard for encoding and communicating structured mathematical information.

The commands in the MathML package support the import and export of both content and presentation MathML.

The Import and Export commands can be used for import and export of MathML files.

Content-Type: application/mathml+xml

$\mathrm{Import}\left(''example/binomial.mml''\,\mathrm{base}=\mathrm{datadir}\right)$

${\left(x+y\right)}^n=\sum _{k=0}^n\left(\genfrac{}{}{0ex}{}{n}{k}\right)x^k{y}^{n-k}$

$\mathrm{MathML}:-\mathrm{Export}\left(\mathrm{sqrt}\left(2{\sin \left(x\right)}^2-1\right)\right)$

$''$ \sqrt{\left(2\⁢{\sin }^2\⁡x-1\right)}$''$
