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