A Canadian math teacher has amazed TikTok users for her incredibly easy trick for multiplying any number by 11.

The teacher, who has earned a huge following across social media platforms under the name Silent Math, frequently shares mathematics help on her channels — including a few speedy tricks to make algebra a breeze.

And in one clip that’s been viewed 25.5 million, she breaks down how to multiply any number in just seconds, without the use of a calculator or pen and paper.

Silent Math, who is based in Ontario, has been teaching math for more than 10 years and offers paid tutoring courses online — as well as plenty of free help on Instagram, YouTube, and TikTok.

In a video shared on March 29, she shared the ’11s trick,’ which makes it easier to multiply another number by 11.

First, you separate the digits of the number you’re multiplying by 11 — so if you’re solving for 11 x 32, you’d separate 32 into 3 and 2.

Then you add those numbers together. For example, 3 plus 2 is 5.

Finally, you put that sum between the two original numbers — so 5 goes between 3 and 2 for 352 — which is the result for 11 x 32.
