Perhaps you should try some spelling variations:
"history in mathematical" » "history in mathematics", "history en matematica", "history con mathematica", "history and mathematical", "history of mathematical"
"history a mathematical" » "history y matematicas", "history la matematica", "history y matematica", "history and mathematical", "history of mathematical"
"history en matematicas" » "history de matematicas", "history las matematicas", "historia en matematicas", "history and matematicas", "history of matematicas"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("history in mathematical") OR ("history a mathematical"))) OR ("history en matematicas"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history in mathematical\") OR (\"history a mathematical\"))) OR (\"history en matematicas\"))*".
• Removing quotes may allow a broader search: (((( history in mathematical ) OR ( history a mathematical ))) OR ( history en matematicas ))*.
