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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("historias de matematica") OR ((("historia del matematica") OR ("historia y mathematica"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"historias de matematica\") OR (((\"historia del matematica\") OR (\"historia y mathematica\"))))*".
• Removing quotes may allow a broader search: (( historias de matematica ) OR ((( historia del matematica ) OR ( historia y mathematica ))))*.
