Perhaps you should try some spelling variations:
"historias de mathematica" » "historias e matematica", "historias da matematica", "historias de marematica", "historia del mathematica"
"historia de matematicas" » "historia las matematicas", "historia la matematicas", "historia en matematicass", "historia y matematicass"
"historia de matematica" » "historia la matematica", "historia en matematicas", "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 mathematica") OR ("historia de matematica"))) OR ("historia de matematicas"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historias de mathematica\") OR (\"historia de matematica\"))) OR (\"historia de matematicas\"))".
• Removing quotes may allow a broader search: (((( historias de mathematica ) OR ( historia de matematica ))) OR ( historia de matematicas )).
• Adding a wildcard symbol may retrieve word variants: (((("historias de mathematica") OR ("historia de matematica"))) OR ("historia de matematicas"))*.
