Perhaps you should try some spelling variations:

"history of matematicas" » "history con matematicas", "history de matematicas", "history y matematicas"
"historia and matematica" » "historia en matematica", "historia la matematica", "historia de matematica", "historia un matematica", "historia una 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 en matematicas\") OR (\"history of matematicas\"))) OR (\"historia and matematica\"))~".
• Removing quotes may allow a broader search: (((( history en matematicas ) OR ( history of matematicas ))) OR ( historia and matematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history en matematicas") OR ("history of matematicas"))) OR ("historia and matematica"))*.
