Perhaps you should try some spelling variations:
"historia de matematicas" » "historia las matematicas"
"history da matematica" » "history la matematica", "history de matematica", "history la matematicas", "history dla matematica", "history dy matematica", "historia da matematica", "history of matematica"
"history a matematica" » "history la matematica", "history y matematica", "history e matematica", "history and matematica", "history of matematica"

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

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