Perhaps you should try some spelling variations:
"history lda matematicas" » "history la matematicas", "history las matematicas", "history de matematicas", "history a matematicas"
"historia de mathematics" » "historia de matematicas", "historia de matematica", "historia in mathematics"
"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 e matematica\") OR (\"history lda matematicas\"))) OR (\"historia de mathematics\"))~".
• Removing quotes may allow a broader search: (((( history e matematica ) OR ( history lda matematicas ))) OR ( historia de mathematics ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history e matematica") OR ("history lda matematicas"))) OR ("historia de mathematics"))*.
