Perhaps you should try some spelling variations:
"historia in mathematical" » "historia in mathematics", "historia en matematicas", "historia en matematica", "historia un mathematical", "historia ii mathematical", "historia con mathematical"
"historia en mathematica" » "historia en matematica", "historia con mathematica", "historia en matematicas", "historia del mathematica", "historia de mathematica", "historia y mathematica"
"history las matematicas" » "history a matematicas"

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 las matematicas\") OR (((\"historia en mathematica\") OR (\"historia in mathematical\"))))~".
• Removing quotes may allow a broader search: (( history las matematicas ) OR ((( historia en mathematica ) OR ( historia in mathematical ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history las matematicas") OR ((("historia en mathematica") OR ("historia in mathematical"))))*.
