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