Use the <math> tag for mathematical formulae and equations, not plain numbers. However, fractions and mixed numbers may be rendered using math.
The <math> tags should be given as
```
<math>\scriptstyle { … }</math>
```
, with the necessary numbers, operations, &c. given in the braces.
The references given, such as in Page:A History of Mathematics (1893).djvu/23, should be given in the format
```
<sup>[[A History of Mathematics/Books of Reference#n|[n]]]</sup>
```
, where the given number replaces n.
Special characters are given in commons:Category:A History of Mathematics (1893).
Other special characters, such as pi (π), etc. should be expressed using <math> tag.
Quoted text (as in this instance) should be rendered using the {{fine block}} template.

Greek
Name	Decimal	Hexadecimal	<math>	Appearance	Notes
Small letter stigma	ϛ	ϛ	\stigma	ϛϛ $\scriptstyle {\mathrm {\stigma} }$	Used to represent 6
Small letter archaic koppa	ϙ	ϙ	\coppa	ϙϙ $\scriptstyle {\mathrm {\coppa} }$	Used to represent 90
Small letter sampi	ϡ	ϡ	\sampi	ϡϡ $\scriptstyle {\mathrm {\sampi} }$	Used to represent 900
Capital letter san	Ϻ	Ϻ	(?)	ϺϺ(?)	Used to represent 10,000
Inverted small letter psi (Corr.: overlaid iota upsilon)	(?)	(?)	(?)	(?)(?) $\scriptstyle {\psi }$ (?)(?) $\scriptstyle {\iota \!\!\!\upsilon }$	Diophantus' symbol for subtraction: According to this site, it is an inverted, overlapped "V" and "I" (regrettably the resulting glyph does not resemble the typography of this book), from the Greek word for "lacking." (Further note: The Errata page indicates the typography should read something like $\scriptstyle {\iota \!\!\!\upsilon }$ , after all!) However this supports the inverted-ψ theory…
Small final sigma	ς	ς	\varsigma	ςς $\scriptstyle {\varsigma }$	(Possibly?) Diophantus' symbol for "unknown" quantities.
