Perhaps you should try some spelling variations:
"historia con mathematical" » "historia con mathematica", "historia con matematicas", "historia in mathematical", "historia como mathematical", "historia en mathematical", "historia un mathematical"
"historia de matematicas" » "historia las matematicas"
"history en matematica" » "history en matematicas", "history la matematica", "history el matematico", "historia en matematica", "history and matematica", "history of matematica"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("history en matematica") OR ((("historia de matematicas") OR ("historia con mathematical"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history en matematica\") OR (((\"historia de matematicas\") OR (\"historia con mathematical\"))))*".
• Removing quotes may allow a broader search: (( history en matematica ) OR ((( historia de matematicas ) OR ( historia con mathematical ))))*.
