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