16 or 1, depending.According to PEMDAS, parentheses come first: 8 ÷ 2 (4)Then, even though multiplication is first in PEMDAS, you go left to right: 4 (4) = 16If you got 1, you’re in good company. That’s what I got at first too but most calculators I’ve tried get 16.I found this at Popular Mechanics and the debate continues online.

I Am Both Safe and Secure

As a whole, I am both safe and secure.
Behead me, I become a place of meeting.
Behead me again, I am the partner of ready.
Restore me, I become the domain of beasts.
