Why Learning Math is Important

i noticed this at walmart some time ago and could not figure out why.

Wal-mart has been carelessly doing this for years. God only knows how things actually ring up. I won't purchase something there if this funny business is going on.

Or you could just look at the orange sticker on each bottle, which appears to be ¢/fl oz.

I work in an independent health food store in Northern Arkansas and we're constantly hearing how we're "just like Wal-Marts", typically because we've either moved something to expand product line or the customer just can't remember where it is. But I seriously fail to see how we're exactly like a corporation that pulls all kinds of ridiculous schemes from top to bottom, just like this one, not to mention sells mostly unhealthy food at prices that really are not that cheap when you're stuck in a town without many other options.

"I hope people can figure out how this theoretical example plays in their own lives."

Yes, I have figured out exactly how this theoretical example plays in my life: it doesn't, because I don't throw milk away 4 days after buying it. Awesome.
