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 e matematicas" » "historia en matematicas", "historia y matematicas", "historia e matematica", "historia del matematicas"

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