Perhaps you should try some spelling variations:
"history con mathematica" » "history in mathematics", "history en matematica", "historia con mathematica", "history of mathematica"
"historias de mathematics" » "historias de matematicas", "historias de matematica", "historias in mathematics", "historia del mathematics"
"historia de mathematics" » "historia de matematicas", "historia de matematica", "historia in mathematics"

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: "((\"history con mathematica\") OR (((\"historias de mathematics\") OR (\"historia de mathematics\"))))~".
• Removing quotes may allow a broader search: (( history con mathematica ) OR ((( historias de mathematics ) OR ( historia de mathematics ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history con mathematica") OR ((("historias de mathematics") OR ("historia de mathematics"))))*.
