5 times! Thats what I think!

Or once, because it ceases to be 30? (Trick question!)

Or, as many times as I like: 30-6=24, 30-6=24, 30-6=24, ... ?

You lie! I can subtract 6 from 30 more than once!

30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6. 30-6.

Etc.

Boy let me tell you what:

I bet you didn't know it, but I'm a fiddle player too.

And if you'd care to take a dare, I'll make a bet with you.

Someone said that already.

Why did the vector cross the road?

It wanted to be normal.
