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