At first glance, this looks like one of the easiest math problems you’ll ever see—but it’s actually catching a lot of people off guard.
The equation is: 10 + 10 + 10 × 0
Most people rush through it and immediately add everything together. But that’s exactly where the mistake happens.
There’s a simple rule in math called the order of operations. It says multiplication must be done before addition. That means you need to solve 10 × 0 first.
And anything multiplied by zero becomes zero.
So now the equation becomes:
10 + 10 + 0
Which gives the final answer: 20
It’s quick, simple, and easy to miss if you’re not paying attention.
That’s why puzzles like this go viral—they look obvious, but they trick your brain in seconds.
So… did you get 20 on your first try?
