Perhaps you should try some spelling variations:
"historia como mathematica" » "historia con mathematica", "historia con matematicas", "historia of mathematics"
"history el matematicos" » "history el matematico", "history en matematicas", "history de matematicas", "historia el matematicos", "history of matematicos", "history a matematicos"
"history and matematica" » "history en matematica", "history en matematicas", "history la matematica"

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 matematicos\") OR (((\"history and matematica\") OR (\"historia como mathematica\"))))~".
• Removing quotes may allow a broader search: (( history el matematicos ) OR ((( history and matematica ) OR ( historia como mathematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history el matematicos") OR ((("history and matematica") OR ("historia como mathematica"))))*.
