This is straight from the solution?

What is the result of the following expression using the precedence rules in Java?
4-2*3/6%2
1. 1
2. 4
3. 3
4. -1
Solution: 3

Hi Doc,

I don`t get it
.. working from left to right the equation becomes
4-(((2*3)/6)%2)
4-((6/6)%2)
4-(1%2)
? 1%2 is 0.5?
4-.5
=3.5?

from assignment1 question 7
6-2*(5+2)%2
6-((2*7)%2)
6-0
6

is my reasoning in line with JAVA lingo?

4-(1%2)
Think in terms of long division as you did in school
