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