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