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