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