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