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