Yes, the answer to that is 16, which isn't the same as 8/2(2+2) (since you added a multiply to it and changed the expression).
No, 8/2 is two terms. I see you didn't read the link about Terms then. If you put 8/2 into brackets, then you just changed the expression, and thus also the answer. According to your logic - add more brackets to the left - 4+8/2(2+2)=(4+8/2)(2+2)=32
My logic is to not add brackets randomly. The equation is 8/2x4. That's it. 2(2) is not (2x2). It's 2x2. The flaw in this equation is that 2(2) is not a proper syntactic equation and is correctly assumed as 2x(2). That's where you're getting confused. If you want to send links and resources here's a link to an EDU article on it, as well as teacher explaining it in a video. Hope this helps and settles this conversation.

The equation is 8/(2x4) - you removed brackets prematurely, violating The Distributive Law
So I see you didn't read the link earlier about The Distributive Law. Try reading it this time around.
I'm not confused at all - I teach this subject and it's what's in every Year 7 Maths textbook. Again, try reading my links.
No, it doesn't, because that's doing division when there's still unsolved brackets, which violates order of operations rules.
Paraphrasing "We forgot about The Distributive Law".
Paraphrasing "We also forgot about Terms". Literally no textbook does what they just said.
Random people ignoring what's in Maths textbooks in regards to a Maths equation would settle it? BWAHAHAHA!
Let me know when you read the links with actual Maths textbooks quoted. Bye now.
