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