Perhaps you should try some spelling variations:
"history en matematica" » "history en matematicas", "history la matematica", "history el matematico", "historia en matematica", "history and matematica", "history of matematica"
"historia y matematica" » "historia y matematicas", "historia y matematico", "historia la matematica", "historia de matematica"
"historia e matematica" » "historia de matematica", "historia de matematicas", "historia en matematicas", "historia en matematica", "historia del matematica"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history en matematica\") OR (\"historia y matematica\"))) OR (\"historia e matematica\"))~".
• Removing quotes may allow a broader search: (((( history en matematica ) OR ( historia y matematica ))) OR ( historia e matematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history en matematica") OR ("historia y matematica"))) OR ("historia e matematica"))*.
