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