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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("historia del matematica") OR ("historia de matematico"))) OR ("historia en matematicas"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historia del matematica\") OR (\"historia de matematico\"))) OR (\"historia en matematicas\"))".
• Removing quotes may allow a broader search: (((( historia del matematica ) OR ( historia de matematico ))) OR ( historia en matematicas )).
• Adding a wildcard symbol may retrieve word variants: (((("historia del matematica") OR ("historia de matematico"))) OR ("historia en matematicas"))*.
