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