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