This mind boggling maths conundrum has got internet users EVERYWHERE scratching their heads.
Looking at the image below, can you work out the pattern in the numbers?
The brain teaser has been shared on Facebook more than 3 million times, with claims that anyone who understands the enigma has an IQ of 150, which is in the top 1 percent and at ‘genius’ level.
Take 9 + 2 = 711. How to you get 711 from those numbers?
9 – 2 = 7
9+2 = 11
Write those two answers next to each other and you get 711.
The other way to look at it is this:
? + ? = 123
If you split the number in two, the answers you need to get are 1 and 23.
See which numbers will add together to make 23, but at the same time are able to be subtracted from one another to give 1.
12 – 11 = 1
12 + 11 = 23
Write them together and you get 123 so the answer is 12 + 11 = 123.
