Question

I am currently learning C Programming ( my first programming language ).
I am a little bit confused with the operators precedence.
Arithmetic operators precedence are as follows.

1. *
2. /
3. %
4. +
5. -

This is what is given in my book at least.
What i am confused is about how do i go solving expressions when it comes to my theory exams ?
I tried solving many expressing with the order given above but fail to get a correct answer.

Given the following definitions:

int a = 10, b = 20, c;

How would we solve this expression?

a + 4/6 * 6/2 

This is an example in my book.

Answer 1

    a + 4/6 * 6/2 
 = 10 + 4/6 * 6/2
 = 10 + 0*6/2
 = 10 + 0/2
 = 10

Note that 4/6 evaluates to 0 as integer division is used.
