Perhaps you should try some spelling variations:
"history en matematica" » "history en matematicas", "history el matematico", "history de matematicas", "historia en matematica", "history and matematica", "history of matematica"
"historia de matematica" » "historia de matematicas", "historia en matematicas", "historia y matematicas"
"history la matematica" » "history las matematicas", "history de matematicas", "history en matematicas", "history a matematica", "historia la matematica", "history of 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 de matematica\"))) OR (\"history la matematica\"))~".
• Removing quotes may allow a broader search: (((( history en matematica ) OR ( historia de matematica ))) OR ( history la matematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history en matematica") OR ("historia de matematica"))) OR ("history la matematica"))*.
