Simple math problem posted on the internet
January 18th, 2018, 05:19
some facebook blah blah had this math problem posted. My wife who has facebook asked me the answer which I said is 19.0000000001
93/1/3+1
now the internet and there was 10,000 answer to this problem including a a math professor from MIT said the answer was 1
if it was 9(3/(1/3))+1 it would be but not as they posted it do you not agree?

It depends on what the "order of operations" would be, that is a thing in math that tells you what order to do things in. I forget the details, but it would probably be able to help.

So if i did 1\3= 0.33333333333
then 3\.33333333=9
99
plus 1
the answer is 1
okay no brackets needed then
then 3\.33333333=9
99
plus 1
the answer is 1
okay no brackets needed then

Maybe it has just been to long for me being in the MATH world that way.

The trick is not about how to solve the puzzle. It's about learning to avoid clickbait.

Do not try to bend the spoon, that's impossible. Instead, only try to realize the truth: there is no spoon.

I made a simple program
answer = 9
edit: No fast replies so I guess I'll go again then
3/1= 3
3/3=1
= 9 1+1 = 9
Code:
answer = 93/1/3+1
edit: No fast replies so I guess I'll go again then
3/1= 3
3/3=1
= 9 1+1 = 9

The answer is to find whoever wrote the calculation like that, and give them detention.

Yes, that depends on how you interprete 3/1/3, which given the character notation isn't entirely clear. Do we mean 3/(1/3) or (3/1)/3. First one gives 1, so the answer is 9, second gives 9 and the answer is 1.
If we wrote it by hand, we would write either
3
______
1
__
3
or
3
__
1
_____
3
But as it stands, at least in computing, we would follow the left to right rule, and the answer is 9.
BTW, using RPN the expression would be unambiguous: 3 1 3 // or 3 1/ 3/

Thanks Pibs, you saved me the time and effort of explaining the 2 possible answers. I'm glad I read all the posts first!!

I'm with pibbur and co.
At school (many years ago) we were taught to do brackets, then exponents, then multiplication and division from left to right, and then addition and subtraction from left to right. This has held for many moons of fixing other peoples' awful financial code.
Seems odd that an MIT prof would get a different answer?
Absent any brackets, that means this:
93/1/3+1
Effectively becomes this:
(9((3/1)/3))+1

The internets is filled with this problem
I tried it with Wolfram Alpha but it didn't give me a smart remark I was expecting.

When written like that, the answer would be 1.
I’ve been taught that a division is to be performed before an addition or subtraction. And the order of operations is from left to right.

I do all my arithmetic in BASECorwin. It keeps all my numbers to a single digit.
