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