Perhaps you should try some spelling variations:
"historias de mathematica" » "historias de matematica", "historias de matematicas", "historias e matematica", "historia de mathematica", "historia del mathematica", "historia y mathematica"
"historia en matematica" » "historia en matematicas", "historia la matematica", "historia de matematica", "historia del matematica", "historia y matematica"
"historia el matematico" » "historia en matematicas", "historia la matematica", "historia del matematico", "historia e matematico", "historia de matematico"

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 de mathematica"))) OR ("historia el matematico"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historia en matematica\") OR (\"historias de mathematica\"))) OR (\"historia el matematico\"))*".
• Removing quotes may allow a broader search: (((( historia en matematica ) OR ( historias de mathematica ))) OR ( historia el matematico ))*.
