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