# Can YOU solve the Quick Math TikTok puzzle in 20 seconds? Accept the challenge now

Attention MATHS nerds, a riddle is making the rounds that will arouse your interest.

And you’ll either be scratching your head – or find out real quick.

But can you solve it in 20 seconds?

This is the challenge of TikToker Super easy math who shared the brain teaser.

The video shows three sums, you still have to figure out a fourth.

But don’t let the addition symbols fool you…

The first seems pretty innocent, with 2 + 4 = 6.

But the next one starts, with 3 +5 = 12.

The last clue is 4 + 6 = 20.

So what is 9 + 11?

If you think 20, you are wrong.

Despite the trick in the first sum, it’s not 2 plus 4, it’s 2 times 4 minus 2… which is also 6.

And the same pattern is continued with the others.

That is, 9 + 11 is … 90.
