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