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

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 matematica"))) OR ("historia de matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historia en matematica\") OR (\"historias de matematica\"))) OR (\"historia de matematica\"))".
• Removing quotes may allow a broader search: (((( historia en matematica ) OR ( historias de matematica ))) OR ( historia de matematica )).
• Adding a wildcard symbol may retrieve word variants: (((("historia en matematica") OR ("historias de matematica"))) OR ("historia de matematica"))*.
