There’s an elementary school problem that can be seen online that only about 90 percent of adults can get right.

The problem is one that features addition, subtraction and division all in one equation. It looks hard, but if you remember a few skills from school, then you can easily solve it in a short time.

If you’re one of the few who can get the problem right, then you have earned bragging rights among your friends. This is one of the equations that many children are bringing home to show their parents and grandparents.

When you look at the problem, you think that it’s easy. All you have to do is complete the actions in the problem to get the answer, right? That’s where you would be wrong.

There is a method to solving the problem. You have to start with anything in parentheses before moving to the multiplication and division. Addition and subtraction are the final steps that you do to complete the problem.

It follows the saying that you might have learned in school called “Please Excuse My Dear Aunt Sally.” If you follow the steps associated with the words, then you’ll get the right answer each time.
