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 mathematics" » "history in mathematics", "history de mathematica"
"historia del matematica" » "historia de matematica", "historia de matematicas", "historia el matematico", "historia y 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 mathematics\") OR (((\"historia con mathematica\") OR (\"historia del matematica\"))))~".
• Removing quotes may allow a broader search: (( history of mathematics ) OR ((( historia con mathematica ) OR ( historia del matematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history of mathematics") OR ((("historia con mathematica") OR ("historia del matematica"))))*.
