The human brain has a lot of stuff to keep track of at all times. It has to take in your surroundings by using your senses, think about what you're going to eat for lunch, wonder if your Instagram photo will get the amount of likes you want and more. And at the same time, the brain is also making you breathe in and out, digest food, and do countless other activities. But sometimes even that's not enough. There are times when your brain craves even more of a challenge.
That's where the brain teaser comes in. For some people a brain teaser can be as simple as trying to understand a pineapple. But there's one brain teaser that's been making the rounds that has been frustrating the people trying to make sense of it.
This person thought the answer could be 3, because that would make each row add up to 9. On the one hand, at least this person used logic to come up with the answer. On the other hand, this answer is also wrong.
And one person thought the empty rectangle should simply stay empty. It already has nothing in it, so why should we feel the need to change it? This answer almost seems profound...but it's still wrong.
Another Twitter user posted this hint that "country kids are more likely to answer this correctly." As another hint, we'll mention that this isn't a math puzzle, so you might want to stop thinking about a number for that final spot. If you don't have it yet, the answer is...
The Twitter user above mentioned "I drive a Manual," so here is the answer. If you drive one, the pattern on this stick shift may burned into your brain, making this puzzle incredibly simple. But if you drive an automatic and aren't too familiar with manual transmission, this brain teaser may have seemed practically impossible.
Of course, if you didn't get the answer right away, nobody has to know. You can always show this to people and say you totally knew it after looking for a couple of seconds. Don't worry, we won't tell on you.
