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