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