Perhaps you should try some spelling variations:
"historia de matematicas" » "historia las matematicas", "historia la matematicas", "historia en matematicas", "historia en matematicass"
"history el matematico" » "history en matematicas", "history la matematica", "historia el matematico", "history of matematico", "history a matematico"
"history de matematica" » "history la matematica", "history en matematica", "history en matematicas", "history of matematica", "history a matematica", "historia del 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 ("historia de matematicas"))) OR ("history de matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history el matematico\") OR (\"historia de matematicas\"))) OR (\"history de matematica\"))*".
• Removing quotes may allow a broader search: (((( history el matematico ) OR ( historia de matematicas ))) OR ( history de matematica ))*.
