Perhaps you should try some spelling variations:
"history con mathematica" » "history en matematica", "history in mathematics", "historia con mathematica"
"history in mathematical" » "history in mathematics", "history en matematicas", "history en matematica", "history and mathematical", "history a mathematical"
"history of mathematica" » "history of mathematics", "history de mathematica", "history la 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 of mathematica\") OR (((\"history in mathematical\") OR (\"history con mathematica\"))))~".
• Removing quotes may allow a broader search: (( history of mathematica ) OR ((( history in mathematical ) OR ( history con mathematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history of mathematica") OR ((("history in mathematical") OR ("history con mathematica"))))*.
