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