Perhaps you should try some spelling variations:
"historia del mathematica" » "historia de mathematica", "historia de matematica", "historia de matematicas", "historia y mathematica"
"historia en matematica" » "historia en matematicas", "historia la matematica", "historia el matematico", "historia de matematica", "historia y matematica", "historias de matematica"
"historias e matematica" » "historias de matematica", "historias y matematica", "historias de matematicas", "historias me matematica", "historia e 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 en matematica") OR ("historias e matematica"))) OR ("historia del mathematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historia en matematica\") OR (\"historias e matematica\"))) OR (\"historia del mathematica\"))*".
• Removing quotes may allow a broader search: (((( historia en matematica ) OR ( historias e matematica ))) OR ( historia del mathematica ))*.
