As you can see, not even a calculator can help you, as it will read the problem wrong and arrive at the answer of 9. To solve it correctly in a calculator, you need to write it out like this: 9-3/(1/3) + 1, which will lead you to 1 as the correct answer. The problem tests your knowledge of PEMDAS, the order of operations formula, which says you must get to the answer by following these steps in this order: parentheses, exponents, multiplication, division, addition, subtraction. In this question, that means dividing 3 by the 1/3 first, which is the same as 3x3. That will then lead you to 9-9+1. PEMDAS states you need to do everything left to right, so then 9-9=0 + 1 = 1. Ta-da!
If you arrived at 3, 7, or 9 as your answer, you're not alone.

My mom wanted me to type up an answer telling how to get the answer. I got it right after a second because I'm a senior in high school and happen to use it frequently. So, don't feel bad if you got it wrong. Also: Rowlet is the best starter for Sun and Moon, She-Hulk is the best character in Marvel Comics, the answer to Life, the Universe, and Everything is 42 (but we must find the question,) and purple is undoubtedly, undeniably the best color. Have a wicked day.

So I asked Jesse to solve this and told him he could post the answer.
As you can see, he is all mine.

I only got it wrong because I forgot to "flip the fraction and then multiply when dividing by fractions" rule. I did remember the proper order of operations though. Can I get half credit?
My problem with this is that there were no parentheses in the original equation.

_______________________________
The reason the solution includes parentheses is because most calculators that most people have can't enter fractions in their native "numerator over denominator" form. If you have a scientific calculator that has fraction input as an option, you could type it in just as it's displayed.
Even without the parenthesis, you have to divide first. Multiplication and Division come before addition or subtraction. After the division, you work it like a normal problem left to right.
Sooooo.
3 divided by 1/3 = 9
9-9+1=1

Me, too.
No. Forgetting to flip the fraction is a critical error.
