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

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

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