There’s no way you remember that far back.
Yeah.
I'm guessing the internet thinks it should be 16?
Lol, the answer is and always has been 16. This has nothing to do with common core, and is not “new math”. You guys either don’t remember order of operations correctly, of you never really understood it.
I taught this stuff for 30 years. It's 16.
Parentheses first, then multiplication and division in the order they occur from left to right. So
8÷2(2+2)
8÷2(4)
4(4)
16
"New math" sucks.
8 ÷ 2X = 1
Solve for X.
It's SOP to type operator symbols with spaces on either side. Whether or not there is a space does not affect order.As originally presented to the Internet (post 46 I believe), there appears to be spaces left and right of the ÷ symbol, and no space between the first 2 and parenthesis. If no space between, you complete the parenthetical first and the correct answer is 1. If you type the whole equation with no spaces, the answer is 16.
Simple, really, it's all about appearances. If I were more purdier, I could give a better answer.

I mean, if you want to change the problem to get a different answer, you could do that.
The problem isn't "2X", it's 2(4) with a division prior to the multiplication. No one is solving for X.

I was just using the X as symbolic, trying to simplify the original equation. Is 8 ÷ 2X = 1 the same as 8 ÷ 2(X) = 1 ?

This is the best explanation I've seen so far.
I think mmpsteve has a valid point in that the lack of a space between the 2 and parentheses is significant. So 2X or 2(X) is not the same as 2 X or 2 (X). Without the space present, I would treat 2X or 2(X) as one term.
