WTF mate?
It's a notation problem. The problem itself is ambiguous, and the fact that the educators can't see that and go on to declare that there was an 'old way' of math that was incorrect shows how retarded and full of themselves the people who devised this curriculum are. But instead of recognizing this is flawed because it's ambiguous, a good amount of goats are just butting heads over whether it's 1 or 16. Good stuff.
The system is making the teachers stupid now.
This is why parentheses are used...to make things unambiguous
Many goats must've learned math from Common Core.
Too tired. Will look again tomorrow.
LOL, Someone linked this in the comments to show that the correct answer is 1: .
I wonder what historical reference they're using that shows that as the old way. You might actually be able to find an old document laying out conventions that would work that way before modern notation was standardized, but I doubt that's what they did. And the fact that the most powerful nation on Earth has its educational facilities telling the kids that both answers are equally correct is just insane.
