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

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

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