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