Have you ever heard of the phrase "dividing zero by zero?" If you've ever tried it on a calculator, things get pretty haywire -- that's because it's impossible to divide a number by 0 since there's nothing to divide, so trying to divide 0 by itself is a massive no-no.
Don't have an iPhone yourself? Here's what happens:
"Imagine that you have zero cookies and you split them evenly among zero friends," Siri answers. "How many cookies does each person get? See? It doesn’t make sense. And Cookie Monster is sad that there are no cookies, and you are sad that you have no friends."
Ouch. HARSH, Siri. All of Twitter thinks so, as a matter of fact:
To be fair, asking a computer to divide by zero can literally cause it to crash -- and HAS, in the case of an expensive U.S. Navy ship that shut down completely in 1997 when a crew member accidentally typed a 0 into their system. Most calculators now are programmed to just give up and call the equation "indeterminate" rather than risk a possible error.
So I don't blame Siri for throwing off some shade when you try to get her to do it herself. It'd be like if someone came up to you and just started reciting Jaden Smith tweets until you passed out.
Be cool to Siri, guys. She puts up with a lot.
