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