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