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