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