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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("history el matematico") OR ("history de matematicas"))) OR ("history da matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history el matematico\") OR (\"history de matematicas\"))) OR (\"history da matematica\"))*".
• Removing quotes may allow a broader search: (((( history el matematico ) OR ( history de matematicas ))) OR ( history da matematica ))*.
