Math is a big topic in the United States, most notably because we’re badly falling behind the rest of the world in terms of mathematical comprehension.

Students in the U.S. are improving but still lagging behind the rest of the world. According to the most recent Pew study, American students scored #35 worldwide in math.

That ain’t good.

This math equation is incredibly unique, not because it’s an interesting problem, but because it went totally viral in Japan. Only 60% of people in their 20’s could answer it. The same question in the 1980’s could be answered by 90% of Americans in their 20’s.

### Can you solve it?

Very smart sum..Ans is 1..

9

It’s minus 1 , I.e. -1

If -1 is the right answer then i can never crack any exam.

Ok, tell me how did you calculate and what’s the right answer

9-3/1/1/3+1= 9-9+1= 1 , is it right sir? :p

No it’s wrong , though your calculation is right. It’s a basic principle of mathematics that when the addition and subtraction are there in place , first consider addition and then subtraction. Hence 9-9+1=9-10=-1

Bhai , this is not the whole equation, there’s a substantial difference. You can see this equation as 9-(3*1/3)+1 , now first you do division and get the out put as 9, now your equation will be 9-(9+1) , that’s a mathematical formula as I told you earlier that do addition first and then subtraction.

-1 would come as answer only in one condition, if there was a bracket after first digit and i didn’t see any bracket there. And, yep, you can take bracket yourself only if there is division or multiplication cause they count as one variable, when there is + or – they’d count as two different variable you can’t take them in bracket yourself.

Well , In that case i need to look at it again. You may be right.

Arre yaar, calculas ka simple rule bhul gya? Jab + or – me equation hoti thi.. to unhe alag alag variable maan ke sidhe differentiate kar dete the.. or jab × or ÷ me hoti to uske lie alag rule hota tha kyunki wo ek hi variable hota tha..

Yaad nai exactly but I remember the sequence (/*+-). Let me ask mathematics genius Mona :p she has master degree in maths. :v

haha, i ain’t even average in calculas and trigonometry but if it comes on algebra or dynamics atleast i’m better than average. :p

Ronak Khandelwal we are not talking about your life asshole :p

Rajat Deshwal bhai you were right, Vo bracket wala Mujhe pata nai tha ki +&- mai Ye nai dekhte unless & until bracket is provided

So you are trying to make stereotypes brain. One for SSC One for HSC One for Engineering One for Medical then Let me know who has brain of kejriwal n rahul, I want to ROFL on their face…

Lol. U need to go bck to school

brackets, x,÷,+, –

Sharon Hazenski Fiorini……3÷1/3 DOES NOT = 9, just saying!

I don’t believe it.

if i’m correct with my math, 3 divided by 1/3 is first. that becomes 3 x 3 = 9. 9-9=0. 0+1=1. but i cant see the cowboy in the drawing or the cigar in the brick wall. ugh.

The answer is 1

1 is correct.
