Perhaps you should try some spelling variations:
"history la matematica" » "history las matematicas", "history de matematicas", "history en matematicas", "history lda matematica", "history le matematica", "history l1 matematica", "historia la matematica", "history of matematica", "historiar la matematica"
"history a matematica" » "history da matematica", "history e matematica", "history 1 matematica", "history and matematica", "history of matematica"
"historia y matematica" » "historia y matematicas", "historia y matematico", "historia de 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 (\"history la matematica\"))) OR (\"historia y matematica\"))~".
• Removing quotes may allow a broader search: (((( history a matematica ) OR ( history la matematica ))) OR ( historia y matematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history a matematica") OR ("history la matematica"))) OR ("historia y matematica"))*.
