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