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