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