re: Solve this math problem

It probably does because it isn't 3 divided by 1 and then divided by 3.
It is 3 divided by 1/3.
No way all of you guys were wrong.

quote:Correct, which is why calculators will tell you 9. They simply solve the equation with zero assumptions
Based purely as written:
3 divided by 1 = 3. 3/3=1. 9-1=8. 8+1=9. The answer is 9.

There are multiple ways to solve this problem depending on order of operations
The frick there is. The whole point of order of operations is that there is one way to correctly solve math.

"Purely as written" is the only way to correctly solve math problems. Anything else is arbitrary nonsense.

Suck it everybody!
In that very explanation the first thing the say is calculators give you 9 
Then they go and change the equation by adding a ()

See I got it even more fricked up. I did
9 – 3/1/3 + 1
= 9 – 3/3 + 1
= 9 – 1 + 1
= 9 - 2
= 7
You know because MDAS addition before subtraction
9 – 3/1/3 + 1
= 9 – 3/3 + 1
= 9 – 1 + 1
= 9 - 2
= 7

It's properly written for anyone that knows how to properly solve a math problem.
The 1/3 was intended to be a fraction, in which case if you're typing it out you have to use either ? or (1/3). Otherwise, if you just type out 3/1/3, it should be evaluated left to right.
Edit: I guess that didn't work, so for those confused that ? should look like an actual 1/3 fraction.

Hey, all Scruffy saw was 3 divided by 1/3.
You were wrong.
You were wrong.

We have a winner.

This is stupid. Why would anyone write it like that. And use multiple division symbols.
Posted on 9/5/17 at 11:22 am to LNCHBOX
This thread is awesome.

I get 9. That's following PEMDAS without inserting parenthesis that aren't there or assuming the 1/3 is a given.
If the problem itself was shitty and it happened to be written, you could call it a shitty written problem. However, if the problem with the problem is the shitty manner in which it was written you should use the adverbial form of the modifier shitty, shittily.
It's all in how you interpret a shittily written problem.

Right off the bat they change the equation by adding parenthesis
