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