Perhaps you should try some spelling variations:
"history and matematica" » "history en matematica", "history en matematicas", "history la matematica"
"historia and matematica" » "historia en matematica", "historia en matematicas", "historia la matematica", "historia un matematica", "historia una matematica"
"history y matematicas" » "history de matematicas", "history en 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history and matematica\") OR (\"history y matematicas\"))) OR (\"historia and matematica\"))~".
• Removing quotes may allow a broader search: (((( history and matematica ) OR ( history y matematicas ))) OR ( historia and matematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history and matematica") OR ("history y matematicas"))) OR ("historia and matematica"))*.
