Perhaps you should try some spelling variations:
"historia in mathematical" » "historia in mathematics", "historia en matematicas", "historia con mathematica", "historia en mathematical", "historia un mathematical", "historia ii mathematical"
"history and mathematics" » "history in mathematics", "history of mathematics"
"history en matematica" » "history en matematicas", "history e matematica", "history la matematica", "historia en matematica", "history of matematica", "history a matematica"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("history en matematica") OR ("history and mathematics"))) OR ("historia in mathematical"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history en matematica\") OR (\"history and mathematics\"))) OR (\"historia in mathematical\"))".
• Removing quotes may allow a broader search: (((( history en matematica ) OR ( history and mathematics ))) OR ( historia in mathematical )).
• Adding a wildcard symbol may retrieve word variants: (((("history en matematica") OR ("history and mathematics"))) OR ("historia in mathematical"))*.
