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