Please help me to understand operator precedence and associativity

Question

I am trying to run following code:
long i = 10;
long k = ++i + i - i - --i ; // here i is pre incremented and decremente
System.out.println(k);
gives output: 4
and
long i = 10;
long k = i++ + i-- - i-- - i-- ; // here i is post incremented and decremente
System.out.println(k);
gives output: 2
Please give me the steps of each evaluation
I mean how this gives output value:
any suggesion highly appreciated

Please give me the steps of each evaluationNo one in their right mind would ever write code this way.
Looks like a certification or homework problem.
