How? Why?
It isn't saying people can't do the math (though some people really can't, and I'm not sure why that deserves chastising. I tutored in college and some people who've had horrendous teachers their whole life and genuinely had to learn the concept of negative numbers probably find it really helpful) it's just there for convenience.
I literally majored in math and I like it. When I'm screaming and on my feet and erratic over the game in the 4th quarter I prefer to just look at the difference than both scores and subtract them.
If you don't like it just ignore it? I don't understand how anyone could have a problem with the diff.
Also Kerr might not understand this, but sometimes alcohol makes math harder than it appears!
