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 matematicas" » "historia de matematicas", "historia en matematicas", "historia las matematicas"
"historia e matematica" » "historia de matematica", "historia y matematica", "historia de 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 matematicas\") OR (\"historia e matematica\"))))~".
• Removing quotes may allow a broader search: (( history en matematica ) OR ((( historia y matematicas ) OR ( historia e matematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history en matematica") OR ((("historia y matematicas") OR ("historia e matematica"))))*.
