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