I have the following problem: $100*\left\{24+100*[1001-4*(25*6+25*4)]\right\}$
I'm very frustrated that I can't solve exercises like this. I have read about PEMDAS and followed the steps but somehow I am making a mistake because the result I get is not correct.(looked at answers in the book).
Can someone provide the steps in order to solve correctly this problem?
