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