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