Perhaps you should try some spelling variations:
"history of matematicas" » "history con matematicas", "history de matematicas", "history en matematicas"
"historia and matematica" » "historia en matematica", "historia en matematicas", "historia la matematica", "historia un matematica", "historia una matematica"
"history 1 matematicas" » "history y matematicas", "history 2 matematicas", "history 3 matematicas", "history a matematicas"

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 of matematicas\") OR (\"history 1 matematicas\"))) OR (\"historia and matematica\"))~".
• Removing quotes may allow a broader search: (((( history of matematicas ) OR ( history 1 matematicas ))) OR ( historia and matematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history of matematicas") OR ("history 1 matematicas"))) OR ("historia and matematica"))*.
