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