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