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