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