Perhaps you should try some spelling variations:
"history and mathematical" » "history en matematicas", "history en matematica", "history in mathematics"
"history in mathematical" » "history in mathematics", "history en matematicas", "history en matematica", "history of mathematical", "history a mathematical"
"historia e matematica" » "historia de matematica", "historia en matematica", "historia y matematica"

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 mathematical"))) OR ("historia e matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history and mathematical\") OR (\"history in mathematical\"))) OR (\"historia e matematica\"))*".
• Removing quotes may allow a broader search: (((( history and mathematical ) OR ( history in mathematical ))) OR ( historia e matematica ))*.
