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