Agreed?


I don't agree due to the shitty structure of the problem, which is the whole point of this stupid thread. Stop saying there is only one "right" way. The whole point is that there isn't.

BTW, you have a funny way of showing something isn't worth arguing by arguing about it for several pages.


I didn't think someone would even question the fact that

9 – 3 ÷ 1/3 + 1 =/= 9 – 3 ÷ (1/3) + 1

Obviously I was wrong.

It's not a fact, which is the fricking point. Jesus. You know this problem is written to be ambiguous, yet here you are arguing there is only one way.

There is one correct answer to the problem in the OP, 9. There is one correct answer to the problem you posted, 1.

Any other answer requires you to assume something that isn't written. If you meant to rewrite the problem from the picture, the OP wrote it incorrectly. He didn't write it poorly, he wrote it incorrectly.

If you were given the question in the OP on a test, written precisely how it appears in the title of this thread, the correct answer is 9.

Nope. But way to keep saying it.

Wrong. They'd either throw the question out or give credit for both answers due to the terrible structure that would never show up in a test setting.

That's cute. Because many people would answer 1, the incorrect answer, you think there is a problem with the question.

9. I’m an engineer


So am I. And the answer is 1, in my estimation.

Here is my reasoning. since the operator ÷ is used to indicate division in the equation, I make the assumption that 1/3 indicates ta fraction so approximately .33333.
As such 3/.3333 or 3/(1/3) is the same as 3 x 3 or 9. So 9-9 + 1=1

If you assume the / is an operator as well, the your answer of 9 is correct. Of course, no engineer I know would have written an equation like that.

I'm not rich but I know a whole lot of stupid millionaires. Money does not equal smarts.

It's factual, because the problem is shite.

There is no functional difference between ÷ and / so the answer is simple:

3 divided by 1 = 3.
3 divided by 3 = 1.
9 minus 1 = 8.
8 plus 1 = 9.

9.

Jesus H Christ.
