Perhaps you should try some spelling variations:
"historia con mathematica" » "historia en matematica", "historia in mathematics", "historia como mathematica", "historia en mathematica", "historia un mathematica"
"history of matematicas" » "history con matematicas", "history de matematicas", "history en matematicas"
"historia de mathematics" » "historia de mathematica", "historia de matematicas", "historia de matematica"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history of matematicas\") OR (((\"historia con mathematica\") OR (\"historia de mathematics\"))))~".
• Removing quotes may allow a broader search: (( history of matematicas ) OR ((( historia con mathematica ) OR ( historia de mathematics ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history of matematicas") OR ((("historia con mathematica") OR ("historia de mathematics"))))*.
