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