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