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