Perhaps you should try some spelling variations:
"history le matematica" » "history de matematica", "history e matematica", "history de matematicas", "history of matematica"
"historia la matematica" » "historia las matematicas", "historia de matematicas", "historia en matematicas", "historia lda matematica", "historia le matematica", "historia ly matematica", "historia de matematica", "historia y matematica", "historia en matematica"
"history a matematica" » "history da matematica", "history e matematica", "history y 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 le matematica") OR ("historia la matematica"))) OR ("history a matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history le matematica\") OR (\"historia la matematica\"))) OR (\"history a matematica\"))".
• Removing quotes may allow a broader search: (((( history le matematica ) OR ( historia la matematica ))) OR ( history a matematica )).
• Adding a wildcard symbol may retrieve word variants: (((("history le matematica") OR ("historia la matematica"))) OR ("history a matematica"))*.
