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", "history a matematica"
"history y matematica" » "history y matematicas", "history y matematico", "history la matematica", "history a matematica", "historia y 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 y matematica") OR ("history de matematica"))) OR ("history con matematicas"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history y matematica\") OR (\"history de matematica\"))) OR (\"history con matematicas\"))".
• Removing quotes may allow a broader search: (((( history y matematica ) OR ( history de matematica ))) OR ( history con matematicas )).
• Adding a wildcard symbol may retrieve word variants: (((("history y matematica") OR ("history de matematica"))) OR ("history con matematicas"))*.
