Perhaps you should try some spelling variations:
"historia in mathematical" » "historia in mathematics", "historia en matematicas", "historia en matematica", "historia en mathematical", "historia un mathematical", "historia ii mathematical"
"history de matematica" » "history de matematicas", "history la matematica", "history en matematica", "history den matematica", "history dy matematica", "history dde matematicas", "historia de matematica", "history of matematica", "history a matematica"
"history e matematica" » "history en matematica", "history y matematica", "history de matematicas", "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 e matematica\") OR (\"history de matematica\"))) OR (\"historia in mathematical\"))~".
• Removing quotes may allow a broader search: (((( history e matematica ) OR ( history de matematica ))) OR ( historia in mathematical ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history e matematica") OR ("history de matematica"))) OR ("historia in mathematical"))*.
