Perhaps you should try some spelling variations:
"history en matematica" » "history en matematicas", "history la matematica", "history el matematico", "historia en matematica", "history and matematica", "history of matematica"
"history de matematica" » "history de matematicas", "history la matematica", "history en matematicas", "historia de matematica", "history of matematica", "historia del matematica"
"history a matematico" » "history y matematico", "history la matematica", "history el matematico", "history and matematico", "history of matematico"

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

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