How was the Roman culture influenced by the Etruscans and the Greeks?

Etruscans influenced Romans by spreading the alphabet in all Italic peninsula, linguistically. They have introduced subtracting numerical system, which was typically to latin and etruscan language, person names made from three names, an advanced social system (etruscans women were appreciated, unlike the roman or athenian ones).

Greeks influenced Romans by myths, religion, culture  and life style.
