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