Cracking the viral maths riddle: Are you smarter than an elementary school student?

Math puzzles and optical illusions are quite popular on the internet. Wrestling with these puzzles has a positive effect on our brain. However, some of them can really make you sweat! An elementary school student will solve the following equation immediately. Older individuals may encounter a few obstacles. But people with a high IQ solve it in just ten seconds. Can you provide the correct answer that swiftly?

Today, we're examining the solution to an equation where spotting a certain pattern is crucial. Once we notice the pattern, finding the solution becomes straightforward.

1+4=5 - in this instance, the answer is obvious, but things become challenging in the next calculations.

2+5 =12

3+6=21

8+11= ?

You have 10 seconds to solve it! Beneath, you can validate if you were able to utilise logical thinking within the given time frame.

First, let's observe the notation 2+5=12. Notice that if we add the result of the initial sum to the numbers on the left, the outcome will be valid. Hence, it becomes: 5+2+5=12.

We solve the subsequent example in a similar fashion: 12+3+6=21

We can now proceed to the final part of the puzzle, once again incorporating the result of the preceding operation: 21+8+11= 40.

Did you compute the correct answer? Splendid! Your IQ is above average and you have the ability to connect facts swiftly. Surely, maths wasn't a stumbling block for you at school.
