Perhaps you should try some spelling variations:
"history of mathematica" » "history of mathematics", "history con mathematica", "history de mathematica"
"historia el matematica" » "historia el matematico", "historia en matematica", "historia e matematica", "historia del matematica", "historia de matematica"
"historia en matematico" » "historia el matematico", "historia en matematica", "historia en matematicas", "historia del matematico", "historia de matematico", "historia y matematico"

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 mathematica\") OR (((\"historia el matematica\") OR (\"historia en matematico\"))))~".
• Removing quotes may allow a broader search: (( history of mathematica ) OR ((( historia el matematica ) OR ( historia en matematico ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history of mathematica") OR ((("historia el matematica") OR ("historia en matematico"))))*.
