These are old classic mathematical problems. When you were in middle or high school.

These tests are more fun when you find yourself trying to remember the math you learned as a child.

Can you figure out the correct solution?

So now I’m going to treat you to a math problem designed for school students. But it’s not that simple for those of us who graduated decades ago. It’s easy to forget the order of operations as we grow older.

The question now: Can you solve this challenge?

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.

Now to the brainteaser – can you figure out the answer? Try to think back on the mathematical rules!

1+1+1+1+1 1+1+1+1+1 1+1×0+1=?

A: 1

B: 21

C: 30

**ANSWER:**

Below we’ll show you the answer.

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.

**The solution is 30.**
