Perhaps you should try some spelling variations:
"history and matematica" » "history en matematica", "history en matematicas", "history la matematica"
"historia of mathematics" » "historia in mathematics", "historia con mathematica", "historia con mathematics", "historia por mathematics", "historia de mathematics"
"historia el matematico" » "historia en matematicas", "historia la matematica", "historia del matematico", "historia en matematico", "historia e matematico"

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 and matematica\") OR (((\"historia el matematico\") OR (\"historia of mathematics\"))))~".
• Removing quotes may allow a broader search: (( history and matematica ) OR ((( historia el matematico ) OR ( historia of mathematics ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history and matematica") OR ((("historia el matematico") OR ("historia of mathematics"))))*.
