Perhaps you should try some spelling variations:
"historias den matematicass" » "historias de matematicas", "historias en matematicas", "historias en matematica", "historias de matematicass", "historias del matematicass", "historia del matematicass"
"historia de matematica" » "historia de matematicas", "historia la matematica", "historia en matematica", "historia den matematica", "historia dy matematica", "historia dde matematicas"
"historia e matematica" » "historia en matematica", "historia y matematica", "historia de matematicas", "historia del matematica"

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

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