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