+ <question>
+ <para>You have learned to replace expressions like e.g. <code
+ language="java">b = b * 4</code> by <code language="java">b *=
+ 4</code>. The following two code snippets should thus be

+ </informaltable>
+
+ <para>Explain the different outcome.</para>
+ </question>
+
+ <answer>
+ <para>The difference is being caused by the *= operator's
+ behaviour with respect to the order of evaluation. The first
+ expression b = b * a / 2 containing two left-associative operators
+ <code>*</code> and <code>/</code> may be rewritten as <code
+ language="java">b = ((b * a) / 2)</code>. We thus get 18 / 2 being
+ equal to 9.</para>
+
+ <para>The second expression <code language="java">b *= a /
+ 2</code> is equivalent to <code language="java">b = (b * (a /
+ 2</code>)). Since the integer division 3 / 2 results in 1 we get
+ the final result 6.</para>
