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