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