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