Perhaps you should try some spelling variations:
"historia por mathematics" » "historia of mathematics", "historia in mathematics", "historia con mathematica", "historia para mathematics", "historico por mathematics", "historia con mathematics"
"historico el matematico" » "historico en matematicas", "historico la matematica", "historico del matematico", "historica el matematico", "historica del matematico", "historico yl matematico"
"historico e matematica" » "historico de matematica", "historico en matematica", "historico y matematica", "historica e 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: "((\"historia por mathematics\") OR (((\"historico el matematico\") OR (\"historico e matematica\"))))~".
• Removing quotes may allow a broader search: (( historia por mathematics ) OR ((( historico el matematico ) OR ( historico e matematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("historia por mathematics") OR ((("historico el matematico") OR ("historico e matematica"))))*.
