You should type in your answers using the same syntax used in the ! symbolic mathematics package, known as a computer algebra system ! (cas), underpinning your implementation.

Note that you do <b>not</b> need ! a semicolon at the end, unlike when you are using a CAS directly. ! <br /><br /></li> ! <li> Use a caret (^) for raising something to a power: for example, ! <font color="BLUE">x<sup>2</sup></font> should be entered as ! <tt><font color="GREEN">x^2</font></tt>. You can get ! a caret by holding down the SHIFT key and pressing the 6 key ! on most keyboards. Negative or fractional powers need brackets: ! enter <font color="BLUE">x<sup>-2</sup></font> as ! <tt><font color="GREEN">x^(-2)</font></tt> ! and <font color="BLUE">x<sup>1/3</sup></font> as ! <tt><font color="GREEN">x^(1/3)</font></tt>. ! <br /><br /></li> ! <li> More generally, when in doubt, use brackets.
