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