you probably won't believe it, but this equals 5!
I must confess .. I don't get it.
EDIT: Or is that the joke?
The joke is ! is factorial, not an exclamation point. So 5! = 5 * 4 * 3 * 2 * 1 = 120 which is also what 25-55+(85+65) equals.
5的阶层就是5 * 4 * 3 * 2 * 1 = 120
Oh. Now I feel stupid (._.)
Oh goddammit that's annoying hahaha. But it's good. I should have known when I got 120 but I was too focused on it not being five. Thanks for keeping me from going batshit.
It took a while before I got it, because, contrary to the use of the word "solve", it was apparently not an equation with "YOU PROBABLY WON'T BELIEVE IT, BUT THIS EQUALS 5!" as the right-hand side.
In the end, it was just about interpreting the "!" as a factorial, which then means that there is a period missing after the sentence.
Well, I'm thoroughly amused

I remember a stupid sales guy promising a client, "If you go with us, you can save $500,000!"
I thought, "No way, dude, my SOA calculator won't even calculate that."
