Perhaps you should try some spelling variations:
"historia in mathematics" » "historia en matematicas", "historia en mathematics", "historia un mathematics", "historia ii mathematics"
"historico den matematica" » "historico de matematica", "historico en matematica", "historico de matematicas", "historico del matematica", "historica de matematica"
"historico e matematica" » "historico de matematica", "historico en matematica", "historico y matematica", "historico a 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: "((\"historia in mathematics\") OR (((\"historico den matematica\") OR (\"historico e matematica\"))))~".
• Removing quotes may allow a broader search: (( historia in mathematics ) OR ((( historico den matematica ) OR ( historico e matematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("historia in mathematics") OR ((("historico den matematica") OR ("historico e matematica"))))*.
