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

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

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