Emelia's basketball team won their game. everyone gave everyone else on the team (5playes in total) a single high five. how many high fives were exchanged?

Well, there are 5 players on each team.

Team A: 5 players (A,B,C,D,E)
Team B: 5 players ( 1,2,3,4,5)

A gave high five to 1,2,3,4,5
B gave high five to 1,2,3,4,5
C gave high five to 1,2,3,4,5
D gave high five to 1,2,3,4,5
E gave high five to 1,2,3,4,5
