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