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