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