1. Supply parenthesis to show how a C compiler would interpret each of the following expressions.
   1. a * b c * d + e
   2. a / b % c / d
2. Give the values of I and j after each of the following expression statements has been executed. Assume that I has the value 1 initially and j has the value 2.
   1. i += j;
   2. i --;
   3. i * j / i;
   4. i % ++j;
3. Use De Morgans Law to write equivalent expressions for each of the following
   1. ! ( x < 8 ) && ! ( y >= 3 )
   2. ! ( x == y ) || ! ( z != 2 )
   3. ! ( ( x <= 3 ) && ( y > 7 ) )
   4. ! ( ( x > 2 ) || ( y <= 4 ) )
