Perhaps you should try some spelling variations:
"historias de matematica" » "historias de matematicas", "historias la matematica", "historias en matematica", "historia de matematica", "historia del matematica"
"historia las matematicas" » "historia la matematicas", "historia da matematicas", "historia es matematicas"
"historia y matematica" » "historia y matematicas", "historia y matematico", "historia la matematica", "historia de matematica"

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

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