+			<li>Math homework, at least for Ms. Lisa Liu's class, is extremely easy.  I wouldn't expect anything harder for other classes in Year 9.  It's literally just vector scaling, vector arithmetic (not even real matrix multiplication), and what... basic linear transformations (i.e. enlargement, stretching, rotation, reflection), translations, and for those who choose to do more than necessary homework (who of course don't have trouble with required homework), basic algebra questions that gives full marks for simply raising an example for a hypothesis instead of proving the hypothesis?  (Ask Me, s22537 Andrew, for a copy.)<br />Yes, each packet is like 15-pages long, but it's literally just a minute per page.  It's really not much.  Heh, you can ask me for some harder ones (a.k.a. Zhongkao Math).  If you can't do that quickly, well that's normal.  If your homework is differnt, tell me.  If you're really having a hard time with math, I'm happy to help (and you should also ask your teacher).  I'm usually at the library during lunchtime.<br />Oh the proof thing is for the optional investigation/whatever-that-is-actually-called packet, which you should ask your teacher for.  Try to prove <span><i>D</i>(<i>x</i>) = <i>D</i>(<i>x</i> + 9<sup><i>n</i></sup>)∀(<i>x</i>, <i>n</i>) ∈ ℤ<sup>+</sup></span>, rather than just giving two examples.</li>
