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