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