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