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