Perhaps you should try some spelling variations:
"history of mathematics" » "history in mathematics", "history con mathematica", "history de mathematica"
"history en matematica" » "history en matematicas", "history la matematica", "history el matematico", "historia en matematica", "history and matematica", "history a matematica"
"historico y mathematics" » "historico in mathematics", "historico y matematicas", "historico y matematica", "historica y mathematics", "historico de mathematics", "historica de mathematics"

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 en matematica\"))) OR (\"historico y mathematics\"))~".
• Removing quotes may allow a broader search: (((( history of mathematics ) OR ( history en matematica ))) OR ( historico y mathematics ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history of mathematics") OR ("history en matematica"))) OR ("historico y mathematics"))*.
