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