Perhaps you should try some spelling variations:
"historia con mathematica" » "historia en matematica", "historia in mathematics", "historia como mathematica", "historia en mathematica", "historia un mathematica"
"historias den matematica" » "historias de matematica", "historias en matematica", "historias de matematicas", "historias del matematica", "historia de matematica"
"historia e matematica" » "historia de matematica", "historia en matematica", "historia y matematica"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("historia con mathematica") OR ((("historias den matematica") OR ("historia e matematica"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"historia con mathematica\") OR (((\"historias den matematica\") OR (\"historia e matematica\"))))".
• Removing quotes may allow a broader search: (( historia con mathematica ) OR ((( historias den matematica ) OR ( historia e matematica )))).
• Adding a wildcard symbol may retrieve word variants: (("historia con mathematica") OR ((("historias den matematica") OR ("historia e matematica"))))*.
