Perhaps you should try some spelling variations:
"history in mathematical" » "history in mathematics", "history en matematicas", "history con mathematica", "history and mathematical", "history a mathematical"
"history of mathematica" » "history of mathematics", "history con mathematica", "history la matematica"
"historia es matematicas" » "historia en matematicas", "historia las matematicas", "historia de matematicas", "historia e matematicas", "historia el 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 of mathematica") OR ("history in mathematical"))) OR ("historia es matematicas"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history of mathematica\") OR (\"history in mathematical\"))) OR (\"historia es matematicas\"))*".
• Removing quotes may allow a broader search: (((( history of mathematica ) OR ( history in mathematical ))) OR ( historia es matematicas ))*.
