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