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