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 la matematica", "history el matematico", "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 en matematica\") OR (\"history in mathematical\"))) OR (\"history in mathematics\"))~".
• Removing quotes may allow a broader search: (((( history en matematica ) OR ( history in mathematical ))) OR ( history in mathematics ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history en matematica") OR ("history in mathematical"))) OR ("history in mathematics"))*.
