Why do I only get 21?17 is correct
Perhaps I am wrong. But I have always worked the problem backwards. So 8-5=3, 5×3=15, 2+15=17.Why do I only get 21?
Asked the wife - mechanical engineering degree. You’re right. She said my logic is right, but my “sequence isn’t. “Whatever is in parenthesis is addressed first”.Perhaps I am wrong. But I have always worked the problem backwards. So 8-5=3, 5×3=15, 2+15=17.
Doing it forward would give you 21.

5+9(6-3)-58-5=3 multiply 5x3=15 add 2 =17 🤷♀️
Yep. That was the acronym she referenced. Never really liked advanced math, so I married someone who did.Do you even Please Excuse My Dear Aunt Sally bro?
I can see how people would get 21 but if you follow PEMDAS it's 17.
