Both are same here.Since the computation takes place based on precedence,here ' * ' has higher precedence over ' - 'therefore first A * B will be calculated and then C * D and finally second quantity will be subtracted from first . In second case exactly the same things are happening as ( ) has higher precedence over any of the operators.
