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