How many perfect scores of 10 did gymnast Nadia Comăneci receive at the 1976 Olympic games?

Nadia Elena Comăneci (born 12 November 1961) is a Romanian retired gymnast and a five-time Olympic gold medalist, all in individual events. During the 1976 Summer Olympics in Montreal she won three gold medals. At the 1980 Summer Olympics in Moscow, she won two more gold medals. During her career, Comăneci won nine Olympic medals and four World Artistic Gymnastics Championship medals.

On 18 July 1976, Comăneci made history at the Montreal Olympics. During the team compulsory portion of the competition, she was awarded the first perfect 10 in Olympic gymnastics for her routine on the uneven bars. However, Omega SA—the traditional Olympics scoreboard manufacturer— was led to believe that it was impossible to receive a perfect ten, thus the scoreboard was not programmed to display that score. Comăneci's perfect 10 thus appeared as "1.00," the only means by which the judges could indicate that she had indeed received a 10.

During the remainder of the Montreal Games, Comăneci earned six additional tens. She won gold medals for the individual all-around, the balance beam and uneven bars. She also won a bronze for the floor exercise and a silver as part of the team all-around. Soviet gymnast Nellie Kim was her main rival during the Montreal Olympics; Kim became the second gymnast to receive a perfect ten for her performance on the vault. Comăneci also took over the spotlight from Olga Korbut, who had been the darling of the 1972 Munich Games.
