Klom Dark: What's this problem with dividing by zero anyway? Anything divided by zero is infinity. Why is that so difficult to comprehend?

The only reason it's not allowed is because the reverse would prove "problematic", so why not just say that multiplication by zero is not allowed rather than shutting down dividing by zero?

No, division by zero is not infinity, division by zero is undefined. It's not "problematic", it's a direct contradiction.

If x / 0 = infinity, then infinity * 0 = x. Clearly an absurd result.

Division is repeated subtraction. You count the number of times you can subtract the number before reaching zero or going negative.

So when you divide by zero, you are attempting to count the number of times you can subtract zero. Which isn't infinity. It's an undefined number because all of the intermediate steps are degenerate. If the answer were truly infinity, then you would HAVE to do it infinity times. But I can subtract 5 times, or subtract a billion, and get the same answer. When any answer fits, it's not infinite, it's undefined.

Klom Dark: That anything divided by nothing is infinity is inherently true

"Feel it in your gut" != inherently true

FTFA: The Roberts campaign released a statement last night touting the high ratings the senator has received from conservative groups like Heritage Action, Americans for Prosperity and the National Rifle Association.

But the Senate Conservatives Fund, which has targeted Republicans it views as insufficiently conservative, signaled last month that Roberts will need to watch his right flank.

So what exactly *is* "righter" than that? Do I want to know?

Pat Roberts is getting a primary challenge for being too liberal? The guy must think Mussolini and Pinochet were filthy communists.
