– Parentheses are done first – Exponents and exponents come next – Multiplication and division (from left to right) – Addition and subtraction (from left to right)
You don’t need to be a math whiz to apply this method. You simply need to remember it. And the good news is, it comes back very quickly!
Let’s break down the operation together, step by step
Let’s start calmly from the beginning. The operation is: 11 – 11 × 11 + 11
Step 1 — We start with the multiplication: 11 × 11 = 121
Step 2 — The expression then becomes: 11 – 121 + 11
Step 3 — We proceed from left to right: 11 – 121 = –110
Step 4 — We finalize: –110 + 11 = –99
The correct answer is therefore –99.
And you, did you find the correct result?
If so, sincere congratulations! Your math skills are perfectly honed and your mathematical foundations are firmly established. If you missed it, don’t beat yourself up — you’re surrounded by millions of people in the same boat. These little challenges exist precisely to remind us that our brains love shortcuts… which don’t always lead to the right place.
What makes these exercises truly valuable is that they go far beyond a simple ego challenge. They boost concentration, reactivate memory, and keep the mind sharp. A kind of mini brain workout, without leaving home or even putting on your sneakers.
The next time this type of challenge pops up on your social media, take a second before scrolling—it might be your chance to shine at the next family dinner!
Mathematics is, above all, a matter of method—and this is one you’ll never forget.
