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