Perhaps you should try some spelling variations:
"history and matematica" » "history en matematica", "history la matematica", "history de matematica", "history ofnd matematica"
"historia en matematicas" » "historia de matematicas", "historia las matematicas", "historia del matematicas", "historia y matematicas"
"history a matematicas" » "history la matematicas", "history y matematicas", "history 1 matematicas", "history of 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 and matematica\") OR (\"history a matematicas\"))) OR (\"historia en matematicas\"))~".
• Removing quotes may allow a broader search: (((( history and matematica ) OR ( history a matematicas ))) OR ( historia en matematicas ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history and matematica") OR ("history a matematicas"))) OR ("historia en matematicas"))*.
