Perhaps you should try some spelling variations:
"history de matematicas" » "history las matematicas", "historia de matematicas", "history of matematicas", "history a matematicas"
"history en matematicas" » "history las matematicas", "history la matematicas", "history el matematicos", "history de matematicas", "history and matematicas", "history of matematicas", "history a matematicas"
"historia en matematica" » "historia la matematica", "historia el matematico", "historia de matematica", "historia del matematica", "historia y matematica"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("historia en matematica") OR ("history de matematicas"))) OR ("history en matematicas"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historia en matematica\") OR (\"history de matematicas\"))) OR (\"history en matematicas\"))*".
• Removing quotes may allow a broader search: (((( historia en matematica ) OR ( history de matematicas ))) OR ( history en matematicas ))*.
