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