Perhaps you should try some spelling variations:
"history lda matematica" » "history la matematica", "history da matematica", "history de matematica", "history ldla matematica", "history ldda matematica", "history lde matematica"
"history lde matematica" » "history de matematica", "history de matematicas", "history la matematica"
"history a matematica" » "history la matematica", "history da matematica", "history e matematica", "history and matematica", "history of 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 lda matematica") OR ("history lde matematica"))) OR ("history a matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history lda matematica\") OR (\"history lde matematica\"))) OR (\"history a matematica\"))".
• Removing quotes may allow a broader search: (((( history lda matematica ) OR ( history lde matematica ))) OR ( history a matematica )).
• Adding a wildcard symbol may retrieve word variants: (((("history lda matematica") OR ("history lde matematica"))) OR ("history a matematica"))*.
