Perhaps you should try some spelling variations:

en mathematics » in mathematics, en matematicas, en matematica
historia ii » historia mis, historia de, historia y
historia en » historia del, historia de, historia y

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 of mathematics ) OR ( historia ii mathematical ))) OR ( historia en mathematics ))~".
• Adding a wildcard symbol may retrieve word variants: (((( history of mathematics ) OR ( historia ii mathematical ))) OR ( historia en mathematics ))*.
