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