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