(This story is fictional)
Today was a very cold and snowy day.
I was texting my weird friend, here's my log:
<[Have you heard the news? Apparently, a famous puzzle was solved today.]
[Oh, I heard alright... I immediately read the article.]>
<[Typical of you.]
<[David, what's the temperature today?]
<[Or more useful, what's the weather?]
<[Reception's pretty bad today. My TV is just static and I can't connect to the weather website, I'm lucky to even hold a chat with you]
[ 7( 0 - 0 )-7 ]>
[Whoops, tried to send that expression but it didn't send. Had to send it again]>
[Anyways, I'll check it out...]>
[It's snowy, and it'll only grow as the day goes on.]>
<[And the temperature?]
David has left the room due to bad ping
The bad weather cut off our conversation. Later on, when we met, I asked for the temperature again, but he told me that he already did. I didn't understand.
Can you tell what the exact temperature was and why? (Celsius)
