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