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