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