Perhaps you should try some spelling variations:
"historias lda matematica" » "historias la matematica", "historias da matematica", "historias de matematica", "historia la matematica", "historias ldla matematica", "historias ldda matematica", "historias lde matematica"
"history of matematica" » "history of mathematics", "history la matematica", "history de matematica"
"history a matematica" » "history la matematica", "history da matematica", "history e matematica", "history and matematica"

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 matematica") OR ((("history of matematica") OR ("historias lda matematica"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history a matematica\") OR (((\"history of matematica\") OR (\"historias lda matematica\"))))".
• Removing quotes may allow a broader search: (( history a matematica ) OR ((( history of matematica ) OR ( historias lda matematica )))).
• Adding a wildcard symbol may retrieve word variants: (("history a matematica") OR ((("history of matematica") OR ("historias lda matematica"))))*.
