Perhaps you should try some spelling variations:
"history de matematica" » "history de matematicas", "history en matematicas", "history y matematicas", "historia de matematica", "history of matematica", "history a matematica"
"history la matematica" » "history las matematicas", "history de matematicas", "history en matematicas", "history a matematica", "historia la matematica", "history of matematica"
"historia y matematico" » "historia y matematica", "historia y matematicas", "historia el matematico", "historia de matematico"

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

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