If you throw 1 ball 0 times, how many balls have been thrown?
That's all P = mv means.
m = number of balls
v = number of times you throw each ball
P = total number of times you throw a ball
So if your math was correct, which it isn't, you are saying that when you throw 10 balls 0 times, you've thrown 10 balls, when in reality you haven't thrown any of them.
You can't just disregard a variable in algebra just because it's value is 0. The variable still has meaning, it's still important.
