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