Perhaps you should try some spelling variations:
"history en matematica" » "history en matematicas", "history el matematico", "history de matematica", "historia en matematica", "history and matematica", "history a matematica"
"history of matematica" » "history of mathematics", "history de matematica", "history y matematica"
"historiar la matematica" » "historiar las matematicas", "historiar de matematicas", "historiar en matematicas", "historia la matematica", "historias la matematica", "historia da 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 ((("history of matematica") OR ("historiar la matematica"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history en matematica\") OR (((\"history of matematica\") OR (\"historiar la matematica\"))))".
• Removing quotes may allow a broader search: (( history en matematica ) OR ((( history of matematica ) OR ( historiar la matematica )))).
• Adding a wildcard symbol may retrieve word variants: (("history en matematica") OR ((("history of matematica") OR ("historiar la matematica"))))*.
