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