Perhaps you should try some spelling variations:
"history of matematica" » "history of mathematics", "history de matematica", "history e matematica"
"historias la matematica" » "historias las matematicas", "historias de matematicas", "historias en matematicas", "historias lda matematica", "historias le matematica", "historias ly matematica", "historia la matematica", "historias a matematica", "historiar la matematica"
"history a matematica" » "history da matematica", "history e matematica", "history y matematica", "history and 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: "((\"history a matematica\") OR (((\"history of matematica\") OR (\"historias la matematica\"))))~".
• Removing quotes may allow a broader search: (( history a matematica ) OR ((( history of matematica ) OR ( historias la matematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history a matematica") OR ((("history of matematica") OR ("historias la matematica"))))*.
