Hello Everyone and welcome to this weeks Viral Math Problem.
This video went viral in Japan a few months back after the media reported that *ONLY* 60% of 20 year olds could arrive
at the correct answer.
The media was surprised at such a low success rate given that Japanese students do very well in international math tests.
In this video, I will introduce you to this viral problem.
We will try to solve it together and also see why it has been generating so much interest.
So here it is, our Viral Math Problem.
9 - 3 / 1 /3 + 1
I want you to do 2 things, please.
Try to solve the problem WITH and then WITHOUT a calculator.
Once you are done, come back and we will look at the solution together.
Ok, good luck and see you shortly.
Welcome back.
The problem looks pretty straight forward.
It has whole numbers and fractions and 3 basic mathematical operations : Addition, Subtraction and Division.
So let us first try solving it using a calculator.
The problem looks simple so I will use a basic calculator and NOT a scientific one.
So lets start entering the problem into this calculator :
9 minus 3 divided by one third and finally plus 1.
The calculator says 9 is the correct answer.
Ok let me pause for a few seconds.
If you see anything wrong with this answer, please mention it in the comment section.
Now let us try solving the problem again, using a calculator but this time, we will be a bit more patient and analytical.
So let us look at our problem again:
9 - 3 / 1 /3 + 1.
Let us separate this portion and give it our attention.
3 divided by 1/3.
So what does this mean?
Well, bring on the visuals….
Let us imagine we have 3 jars of water.
And we have some plants and each plant needs 1/3 of a jar of water
So how many plants can we water using our 3 jars?
Let us visualise this:
So we have our 3 jar.s And now let us divide each jar into 3 equal parts
as you can see, 1 jar , can , water 3 plants.
So three jars can water 9 plants. right.
So what we are basically seeing is that 3 divided by one third can be written as
3 multiplied by 3 divided by 1 or just 3 multiplied by 3.
Now with this knowledge , let us go back to our problem and change it.
Our problem can also be written as follows
9 - 3 into 3 + 1
Now we can easily solve this ourselves but let us first feed it to the calculator.
We should get the same result as previously, right. Lets check it out…
Hmm. We get one..This is different from our first answer, which was 9.
So why did we get a different answer the first time?
To answer this question, lets quickly revisit the original problem.
So here is our problem once again:
9 - 3 / 1 /3 + 1
When we entered the problem into the calculator for the first time, the calculator did not understand that the fraction one third needed to be grouped
together.
So it calculated the value of 3 / 1 /3 which gave us 1 and which is incorrect.
Let us now tell the calculator to group the 1 third together and see what happens:
As you just saw, the calculator evaluated the 1/3 first as per PEMDAS rules
So we got
9 - 3 / 0.333 + 1
And this results in 1, which is the correct answer.
Did you figure this out?
Please let me know what you thought of this video. I would love to hear from you.

What Is 60÷5(7-5) = ? The Viral Problem Everyone Is Arguing About

What is 60÷5(7-5) = ? Everyone is arguing about this problem, so let's figure out the correct answer! The problem involves the order of operations, historical math notation, and binary expression trees. Glad to see the world is passionate about mathematics!

Here is a 1917 article from The American Mathematical Monthly that explains the usage of the division symbol as an exception to the order of operations

How to solve 9-3➗1/3+1 to get the correct answer...

Here is the another viral math problem..this math problem went viral in japan and it was found that 60 percent of people were not able to solve it..Moreover this problem is based on order of operations..we have a set of rules which tell us which operation should be applied first and by applying these rules only then we can get the the correct answer otherwise we can get the wrong answer...So it is necessary to apply these set of rules to get correct answer...it is easy to remember these set of rules by an acronym called BODMAS where B stands for bracket,O stands for of/exponential,D stands for division,M stands for multiplication,A stands for addition and s stands for subtraction...For more explanation watch the video till end..Hope it will help you to understand these rules....
