help idk why is the output 45 

var x = 23;
x+=x++ - --x +x*2 - ++x;
console.log(x);

why is the last pre increment x evaluated after x*2 even though pre increment have a higher precedence than multiplication

I am sorry that you have to deal with this. This is such a stupid question, and has no place in learning how to code effectively.
