@ought-six: Nossir. Look closely at Leep's sentence. He knows ten times as much as someone who doesn't know nothing
That means that the knowledge is non-zero. It is not nothing.
Ergo, the math reads more correctly as: 10 x NonZeroNumber = 10NonZeroNumber.
@Leep: You crafty son-of-a-bitch, you. 😊
Yes, you’re right if one is speaking grammatically.
However, the proper use of grammar is something that is alien to most Americans; and the double negative has become so accepted in the American lexicon that when one encounters it, one assumes the intent was not a negation, but rather an affirmation.
I posit that Leep’s intent was the latter.
Isn’t this fun?
