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