Mathematical dilemma?
I don't know why I can't understand it but how does this:
5^2 - (4^2 - 3^2) + 14/2 - 6/3
Equal -19?
Every time I try it I end up with 23, I even used a scientific calculator and got 23 as well. Can some please show me how to do this problem so that I can know what I'm doing wrong?

N^2 = N*N
5^2 - (16 - 9) + 14/2 - 6/3...............do what is in ( ) 1st.......4^2 = 4*4=16 and 3^2 = 3*3 =9
5^2 - (7) + 14/2 - 6/3.......................do powers and roots second...5^2 = 5*5 = 25
25 - (7) + 14/2 - 6/3........................do multiplication and division 3rd working left to right
25 - 7 + 7 - 2..................................last do addition and subtraction working left to right
18 + 7 - 2
25 - 2
23
You are doing nothing wrong.,
I have not a single idea how anyone could get -19 out of this
expression.
I can't see how it does. I get 23, as well.
If someone is getting 19, it is most likely because they are not taking into account PEMDAS.
in a totally unrelated topic...COOL STORY BRO!
