Perhaps you should try some spelling variations:
"history and matematica" » "history en matematica", "history en matematicas", "history la matematica"
"history el matematico" » "history en matematicas", "history la matematica", "history of matematico", "history a matematico", "historia del matematico"
"historia el matematico" » "historia en matematicas", "historia la matematica", "historia del matematico", "historia en matematico", "historia e 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 el matematico\") OR (\"historia el matematico\"))) OR (\"history and matematica\"))~".
• Removing quotes may allow a broader search: (((( history el matematico ) OR ( historia el matematico ))) OR ( history and matematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history el matematico") OR ("historia el matematico"))) OR ("history and matematica"))*.
