MathML deals not only with the ''presentation'' but also the ''meaning'' of formula components (the latter part of MathML is known as "Content MathML"). Because the meaning of the equation is preserved separate from the presentation, how the content is communicated can be left up to the user. For example, web pages with MathML embedded in them can be viewed as normal web pages with many browsers, but visually impaired users can also have the same MathML read to them through the use of [[screen readers]] (e.g. using the [[VoiceOver]] in [[Safari_(web_browser) | Safari]]). [[JAWS (screen reader)|JAWS]] from version 16 onward supports MathML voicing as well as braille output.<ref>{{Cite web|title=JAWS Version 16|url=https://support.freedomscientific.com/downloads/jaws/JAWSWhatsNew?version=16|url-status=live}}</ref>

The quality of rendering of MathML in a browser depends on the installed fonts. The [[STIX Fonts project]] have released a comprehensive set of mathematical fonts under an open license. The [[Cambria Math]] font supplied with Microsoft Windows had a slightly more limited support.<ref name="Vismor">{{Citation|url=https://vismor.com/documents/site_implementation/viewing_mathematics/viewing_mathematics.php|title=Viewing Mathematics on the Internet|access-date=13 April 2011|first=Timothy|last=Vismor}}</ref>

A valid MathML document typically consists of the XML declaration, [[Document type declaration|DOCTYPE]] declaration, and document element.
