 <li>statements are assignments or the final expression to return</li>
 <li>an assignment starts a statement, it is not an operator</li>
 <li>assignments to built-ins do not throw an exception and have no effect;  e.g. <kbd>r=3.0; r</kbd> returns the pixel red color value, not 3.0</li>
+<li>Unary operators have a lower priority than binary operators, that is, the unary minus (negation) has lower precedence than exponentiation, so -3^2 is interpreted as -(3^2) = -9.  Use parentheses to clarify your intent (e.g. (-3)^2 = 9).</li>
+<li>Similarly, care must be exercised when using the slash ('/') symbol. The string of characters <em>1/2x</em> is interpreted as (1/2)x. The contrary interpretation should be written explicitly as 1/(2x). Again, the use of parentheses helps clarify the meaning and should be used whenever there is any chance of misinterpretation.</li>
