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