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