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