Perhaps you should try some spelling variations:
"history and mathematical" » "history in mathematical", "history en matematicas", "history en matematica"
"history in mathematics" » "history en matematicas", "history en matematica", "history of mathematics", "history a mathematics"
"historia las matematicas" » "historia la matematicas", "historia da matematicas", "historia es matematicas"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("history and mathematical") OR ("history in mathematics"))) OR ("historia las matematicas"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history and mathematical\") OR (\"history in mathematics\"))) OR (\"historia las matematicas\"))*".
• Removing quotes may allow a broader search: (((( history and mathematical ) OR ( history in mathematics ))) OR ( historia las matematicas ))*.
