Perhaps you should try some spelling variations:
"history and mathematics" » "history in mathematics", "history of mathematics"
"historia en matematica" » "historia en matematicas", "historia e matematica", "historia la matematica", "historia del matematica", "historia de matematica", "historia y matematica"
"history 1 matematicas" » "history y matematicas", "history 2 matematicas", "history 3 matematicas", "history a matematicas", "history of 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 en matematica") OR ((("history and mathematics") OR ("history 1 matematicas"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"historia en matematica\") OR (((\"history and mathematics\") OR (\"history 1 matematicas\"))))".
• Removing quotes may allow a broader search: (( historia en matematica ) OR ((( history and mathematics ) OR ( history 1 matematicas )))).
• Adding a wildcard symbol may retrieve word variants: (("historia en matematica") OR ((("history and mathematics") OR ("history 1 matematicas"))))*.
