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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("historia el matematico") OR ("history of mathematica"))) OR ("history en matematicas"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historia el matematico\") OR (\"history of mathematica\"))) OR (\"history en matematicas\"))".
• Removing quotes may allow a broader search: (((( historia el matematico ) OR ( history of mathematica ))) OR ( history en matematicas )).
• Adding a wildcard symbol may retrieve word variants: (((("historia el matematico") OR ("history of mathematica"))) OR ("history en matematicas"))*.
