Perhaps you should try some spelling variations:
"history de matematica" » "history de matematicas", "history la matematica", "history en matematicas", "historia de matematica", "history of matematica", "historia del matematica"
"history a matematica" » "history la matematica", "history da matematica", "history y matematica", "history and matematica", "history of matematica"
"historia y matematico" » "historia y matematica", "historia y matematicas", "historia el matematico", "historia de matematico"

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 de matematica\") OR (\"history a matematica\"))) OR (\"historia y matematico\"))~".
• Removing quotes may allow a broader search: (((( history de matematica ) OR ( history a matematica ))) OR ( historia y matematico ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history de matematica") OR ("history a matematica"))) OR ("historia y matematico"))*.
