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