Perhaps you should try some spelling variations:
"history of mathematics" » "history in mathematics", "history con mathematica", "history de mathematica"
"history en matematica" » "history en matematicas", "history la matematica", "history el matematico", "historia en matematica", "history and matematica", "history a 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history en matematica\") OR (((\"history de matematica\") OR (\"history of mathematics\"))))~".
• Removing quotes may allow a broader search: (( history en matematica ) OR ((( history de matematica ) OR ( history of mathematics ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history en matematica") OR ((("history de matematica") OR ("history of mathematics"))))*.
