**We all learned math in school. Some were better than others, but most still managed to understand the basics. Some people have continued learning more complex math in university, but most of us stopped after high school.**

**I myself am content with the math I learned in high school, which is still a solid foundation to rely on. But when letters and tricky formulas started showing up, I felt that it got a bit overwhelming.**

It’s usually enough for everyday life to know the four basic arithmetic operations – addition, subtraction, multiplication, and division.

Of course, there are always those looking a new impossible equation, problem, or challenge, that we mere mortals are just happy to ignore.

## Most people get it wrong

At the same time, even the most basic math can be forgotten when you don’t practice. With that in mind, I thought we could leave the regular puzzles aside for a second to try to refresh the basic skills you learned back in school.

For this problem, it’s essential to remember the order of operations while also having a good eye for detail. It’s not an easy task – and according to most sites online, most people get it wrong on their first try.

Can you figure out the solution?

Time to use that head of yours.

Yeah, it’s actually not that simple, but as I said, not even 50% get it right at first.

## Here is the solution

Below we’ll show you the answer.

Make sure you have a number in mind before seeing the result after this picture!

*The answer is 30.*

You get this if you see that the ones at the end of each row have no sign between them and the next one.

Therefore, they are actually 11s.

The “1 x 0” on the last line becomes 0. Multiplication must always be solved before addition if there are no **parentheses**.
