It’s to that end that we decided to put the minds of our beloved readers to the test, with a bran-teasing issue that’s left plenty of people across the internet scratching their heads.
If 1+4=5, 2+5=12, and , then what is the value of 5+8?
Perhaps it’s easier if you see it written out as follows:
1+4=5
2+5=12
3+6=21
5+8=?
It appears that this particular problem has left a large portion of the internet scratching their heads, and a lot of people split on what the correct answer actually is. Much of it depends on how you approach the exercise of course; what exact method you employ to try and help you find the right answer.
And the crux of it all? There’s more than one correct answer! In fact, there are quite a few if our research is anything to go by. If you’ve had a go at the problem yourself and want to see if you’ve got it right (or if, like me, you were ultimately left so frustrated that you simply have to be given the answer) see below for five different ways the problem can be tackled.
