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