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