Perhaps you should try some spelling variations:
"historia and matematica" » "historia en matematicas", "historia la matematica", "historia de matematica", "historia en matematica", "historia un matematica", "historia una matematica"
"history en matematica" » "history en matematicas", "history e matematica", "history la matematica", "historia en matematica", "history and matematica", "history of matematica"
"history a matematicas" » "history la matematicas", "history y matematicas", "history 1 matematicas", "history and 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 en matematica\") OR (\"history a matematicas\"))) OR (\"historia and matematica\"))~".
• Removing quotes may allow a broader search: (((( history en matematica ) OR ( history a matematicas ))) OR ( historia and matematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history en matematica") OR ("history a matematicas"))) OR ("historia and matematica"))*.
