ELI5:how is boxing scored

Why is floyd mayweather winning when he isn't taking initiative or throwing more punches? How do they decide each round and how do they decide the overall winner?

Boxing is most commonly scored with the winner of a round being given a 10 and the loser a 9.  A draw gives both a 10.  Any knockdowns mean another point is deducted from that boxer.  Once that score is established, any point deductions for fouls called by the referee are calculated in, so that if the winner has a foul called, the score becomes 9-9.

Examples:
X wins a round over Y: 10(X) -  9(Y)

X wins a round, knocking down Y twice: 10(X) - 7(Y)

X wins a round, knocking down Y, but also committing a foul: 9(X) - 8(Y)



The winner of a round is basically determined by who landed more "clean" punches.  Shots that just graze the body or get blocked are "worth" far less than a clean punch to the body or head.  It's better to land a few solid punches that to be continuously throwing misses or into guards.
