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