Perhaps you should try some spelling variations:
"history of mathematics" » "history in mathematics", "history con mathematica"
"historia es matematicas" » "historia en matematicas", "historia las matematicas", "historia de matematicas", "historia e matematicas", "historia el matematicas"
"history la matematica" » "history las matematicas", "history de matematicas", "history en matematicas", "history a matematica", "historia la matematica", "historiar la matematica"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history of mathematics\") OR (((\"history la matematica\") OR (\"historia es matematicas\"))))~".
• Removing quotes may allow a broader search: (( history of mathematics ) OR ((( history la matematica ) OR ( historia es matematicas ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history of mathematics") OR ((("history la matematica") OR ("historia es matematicas"))))*.
