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