Why is it important to know PEMDAS as a mathematician?

So everyone can solve every problem the same (correct) way.

5 2 + 1=11
5 2 = 25, not 10. Correct Answer is 26.

What is the saying we use to remember the correct Order of Operations?

Please Excuse My Dear Aunt Sally.

The problem was 20 - 5 x 2 + 3. My answer was 33. What did I do wrong?

I went from left to right without using the correct order of operations.

10 3  = 30

10 3  = 10 x 10 x10, which is 1000, not 30.
