Perhaps you should try some spelling variations:
"history and mathematics" » "history in mathematics", "history of mathematics"
"historia un mathematical" » "historia in mathematical", "historia en matematicas", "historia in mathematics", "historia con mathematical", "historia de mathematical", "historia y mathematical"
"historia en mathematica" » "historia en matematica", "historia con mathematica", "historia in mathematical", "historia del mathematica", "historia de mathematica", "historia 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 and mathematics\") OR (((\"historia en mathematica\") OR (\"historia un mathematical\"))))~".
• Removing quotes may allow a broader search: (( history and mathematics ) OR ((( historia en mathematica ) OR ( historia un mathematical ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history and mathematics") OR ((("historia en mathematica") OR ("historia un mathematical"))))*.
