Perhaps you should try some spelling variations:
"historia en matematicas" » "historia de matematicas", "historia las matematicas", "historia del matematicas", "historia y matematicas"
"historia and matematica" » "historia en matematica", "historia la matematica", "historia de matematica", "historia un matematica", "historia una matematica", "history and 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 matematicas") OR ("history 1 matematicas"))) OR ("historia and matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historia en matematicas\") OR (\"history 1 matematicas\"))) OR (\"historia and matematica\"))*".
• Removing quotes may allow a broader search: (((( historia en matematicas ) OR ( history 1 matematicas ))) OR ( historia and matematica ))*.
