NBCIt seems that they push primary school kids in Singapore a lot harder than they do in the UK.
While we were making unidentifiable models from lolly sticks, six-year-old children in Southeast Asian city state were figuring out this ridiculously difficult maths puzzle.
The photo of the maths question was posted on Twitter and has left adults all over the world scratching their brains at what the numbers in the circles could be.
Apparently, this math question appeared in an exam for Grade Ones in Singapore. Lets see who can solve it.

Many have claimed that the number two should in fact be a 20.
Due to the open-ended nature of the question, there are actually numerous correct answers to this puzzle.
15+3+0=18 0+3+7=10 7+3+2=12. 2+3+15=20 pic.twitter.com/phFJbUCc6o

The most common was (if the two was a 20), then the number in between the two circles would be the sum of them plus three.
2+3=5 / 18+3= 21 / 10+3=13
12+3=15 pic.twitter.com/rhU5tVDRyU— John Hunton (@hunton_john) May 18, 2017
Another answer was that the numbers in the circles add up to the one in-between, making the three redundant.
Yes, there is a TYPO :- That 2 should be written as 20 otherwise this sum is invalid.
Top circle is 6
Left=9
Right=1
Bottom=8— Ritesh dalai (@Riteshdalai1) May 19, 2017
Then this guy went rogue and made it so that the sum is always 24 whether it is done vertically or horizontally.
Top no. 14
Left no. 10
Right no. 11
Bottom no. 7
Sum is always 24 (vertical or horizontal)— DEEPESH AJMERA (@DEEP1509) May 18, 2017
So there are numerous ways to do this test, and there is potentially an error.
I thought the good thing about maths is that there is only one right answer.
