There are 2 questions in this document, accompanied by some instructions.

Copy this document into a word processor or text

editor.

Answer the two questions posed in this document,

inserting your answers, confidence assessments and

self-critiques as explained.

Solutions are given, but don't look at the solution

to a question or problem until you have entered

your answer.

You will probably find that you can answer many of

these questions without writing anything down.

It is often helpful to sketch, doodle, jot down

ideas, do calculations, organize and test ideas on

paper. On those problems where you cannot arrive

at an answer 'in your head', is recommended that

you work out your solutions on paper.

When appropriate, you will later be encouraged to

use a calculator to do any arithmetic you cannot do

mentally. However the calculator is not

appropriate to the questions that appear on this

document. Put the calculator aside and think

through these questions.

When you are finished you will submit your work

according to the instructions at the end of this

document.

It is important that all the information in

documents of this nature be submitted, so that all

the information ends up posted at your page.

When submitting documents, do not delete anything

from the original document. Insert your answers,

questions, comments, etc. as indicated, but do not

otherwise change the original document.
