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