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