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