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