where do i put parentheses: 8*4-2*5+4/2

Question

I need this question answered!!!

Answer 1

You don’t need parentheses if the order of operations follows PEMDAS or BODMAS priority rules.

In this case we would get: 32-10+2=24 because the multiplication and division operations are done first.

But you can make this more explicit by using parentheses:

(8*4)-(2*5)+(4/2). When you do this it leaves no doubt about what is intended.

The result is so different if we do this, for example:

8*(4-2)*(5+4)/2=16*9/2=72.
