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