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