Perhaps you should try some spelling variations:
"history of mathematics" » "history in mathematics", "history con mathematica", "history de mathematica"
"history and matematica" » "history en matematica", "history en matematicas", "history la matematica"
"historico un mathematica" » "historico con mathematica", "historico in mathematical", "historico en matematica", "historica una mathematica", "historico de mathematica", "historico y mathematica"

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