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